## PG 18Beta1–related changes for building Citus
### TupleDesc / Attr layout
**What changed in PG:** Postgres consolidated the
`TupleDescData.attrs[]` array into a more compact representation. Direct
field access (tupdesc->attrs[i]) was replaced by the new
`TupleDescAttr()` API.
**Citus adaptation:** Everywhere we previously used
`tupdesc->attrs[...]`, we now call `TupleDescAttr(tupdesc, idx)` (or our
own `Attr()` macro) under a compatibility guard.
*
5983a4cffc
General Logic:
* Use `Attr(...)` in places where `columnar_version_compat.h` is
included. This avoids the need to sprinkle `#if PG_VERSION_NUM` guards
around each attribute access.
* Use `TupleDescAttr(tupdesc, i)` when the relevant PostgreSQL header is
already included and the additional macro indirection is unnecessary.
### Collation‐aware `LIKE`
**What changed in PG:** The `textlike` operator now requires an explicit
collation, to avoid ambiguous‐collation errors. Core code switched from
`DirectFunctionCall2(textlike, ...)` to
`DirectFunctionCall2Coll(textlike, DEFAULT_COLLATION_OID, ...)`.
**Citus adaptation:** In `remote_commands.c` and any other LIKE call, we
now use `DirectFunctionCall2Coll(textlike, DEFAULT_COLLATION_OID, ...)`
and `#include <utils/pg_collation.h>`.
*

### Columnar storage API
* Adapt `columnar_relation_set_new_filelocator` (and related init
routines) for PG 18’s revised SMGR and storage-initialization hooks.
* Pull in the new headers (`explain_format.h`,
`columnar_version_compat.h`) so the columnar module compiles cleanly
against PG 18.
- heap_modify_tuple + heap_inplace_update only exist on PG < 18; on PG18
the in-place helper was removed upstream

### OpenSSL / TLS integration
**What changed in PG:** Moved from the legacy `SSL_library_init()` to
`OPENSSL_init_ssl(OPENSSL_INIT_LOAD_CONFIG, NULL)`, updated certificate
API calls (`X509_getm_notBefore`, `X509_getm_notAfter`), and
standardized on `TLS_method()`.
**Citus adaptation:** We now `#include <openssl/opensslv.h>` and use
`#if OPENSSL_VERSION_NUMBER >= 0x10100000L` to choose between`
OPENSSL_init_ssl()` or `SSL_library_init()`, and wrap`
X509_gmtime_adj()` calls around the new accessor functions.

### Adapt `ExtractColumns()` to the new PG-18 `expandRTE()` signature
PostgreSQL 18
80feb727c8
added a fourth argument of type `VarReturningType` to `expandRTE()`, so
calls that used the old 7-parameter form no longer compile. This patch:
* Wraps the `expandRTE(...)` call in a `#if PG_VERSION_NUM >= 180000`
guard.
* On PG 18+ passes the new `VAR_RETURNING_DEFAULT` argument before
`location`.
* On PG 15–17 continues to call the original 7-arg form.
* Adds the necessary includes (`parser/parse_relation.h` for `expandRTE`
and `VarReturningType`, and `pg_version_constants.h` for
`PG_VERSION_NUM`).
### Adapt `ExecutorStart`/`ExecutorRun` hooks to PG-18’s new signatures
PostgreSQL 18
525392d572
changed the signatures of the executor hooks:
* `ExecutorStart_hook` now returns `bool` instead of `void`, and
* `ExecutorRun_hook` drops its old `run_once` argument.
This patch preserves Citus’s existing hook logic by:
1. **Adding two adapter functions** under `#if PG_VERSION_NUM >=
PG_VERSION_18`:
* `citus_executor_start_adapter(QueryDesc *queryDesc, int eflags)`
Calls the old `CitusExecutorStart(queryDesc, eflags)` and then returns
`true` to satisfy the new hook’s `bool` return type.
* `citus_executor_run_adapter(QueryDesc *queryDesc, ScanDirection
direction, uint64 count)`
Calls the old `CitusExecutorRun(queryDesc, direction, count, true)`
(passing `true` for the dropped `run_once` argument), and returns
`void`.
2. **Installing the adapters** in `_PG_init()` instead of the original
hooks when building against PG 18+:
```c
#if PG_VERSION_NUM >= PG_VERSION_18
ExecutorStart_hook = citus_executor_start_adapter;
ExecutorRun_hook = citus_executor_run_adapter;
#else
ExecutorStart_hook = CitusExecutorStart;
ExecutorRun_hook = CitusExecutorRun;
#endif
```
### Adapt to PG-18’s removal of the “run\_once” flag from
ExecutorRun/PortalRun
PostgreSQL commit
[[3eea7a0](3eea7a0c97)
rationalized the executor’s parallelism logic by moving the “execute a
plan only once” check into `ExecutePlan()` itself and dropping the old
`bool run_once` argument from the public APIs:
```diff
- void ExecutorRun(QueryDesc *queryDesc,
- ScanDirection direction,
- uint64 count,
- bool run_once);
+ void ExecutorRun(QueryDesc *queryDesc,
+ ScanDirection direction,
+ uint64 count);
```
(and similarly for `PortalRun()`).
To stay compatible across PG 15–18, Citus now:
1. **Updates all internal calls** to `ExecutorRun(...)` and
`PortalRun(...)`:
* On PG 18+, use the new three-argument form (`ExecutorRun(qd, dir,
count)`).
* On PG 15–17, keep the old four-arg form (`ExecutorRun(qd, dir, count,
true)`) under a `#if PG_VERSION_NUM < 180000` guard.
2. **Guards the dispatcher hooks** via the adapter functions (from the
earlier patch) so that Citus’s executor hooks continue to work under
both the old and new signatures.
### Adapt to PG-18’s shortened PortalRun signature
PostgreSQL 18’s refactoring (see commit
[3eea7a0](3eea7a0c97))
also removed the old run_once and alternate‐dest arguments from the
public PortalRun() API. The signature changed from:
```diff
- bool PortalRun(Portal portal,
- long count,
- bool isTopLevel,
- bool run_once,
- DestReceiver *dest,
- DestReceiver *altdest,
- QueryCompletion *qc);
+ bool PortalRun(Portal portal,
+ long count,
+ bool isTopLevel,
+ DestReceiver *dest,
+ DestReceiver *altdest,
+ QueryCompletion *qc);
```
To support both versions in Citus, we:
1. **Version-guard each call** to `PortalRun()`:
* **On PG 18+** invoke the new 6-argument form.
* **On PG 15–17** fall back to the legacy 7-argument form, passing
`true` for `run_once`.
### Add support for PG-18’s new `plansource` argument in
`PortalDefineQuery`**
PostgreSQL 18 extended the `PortalDefineQuery` API to carry a
`CachedPlanSource *plansource` pointer so that the portal machinery can
track cached‐plan invalidation (as introduced alongside deferred-locking
in commit
525392d572.
To remain compatible across PG 15–18, Citus now wraps its calls under a
version guard:
```diff
- PortalDefineQuery(portal, NULL, sql, commandTag, plantree_list, NULL);
+#if PG_VERSION_NUM >= 180000
+ /* PG 18+: seven-arg signature (adds plansource) */
+ PortalDefineQuery(
+ portal,
+ NULL, /* no prepared-stmt name */
+ sql, /* the query text */
+ commandTag, /* the CommandTag */
+ plantree_list, /* List of PlannedStmt* */
+ NULL, /* no CachedPlan */
+ NULL /* no CachedPlanSource */
+ );
+#else
+ /* PG 15–17: six-arg signature */
+ PortalDefineQuery(
+ portal,
+ NULL, /* no prepared-stmt name */
+ sql, /* the query text */
+ commandTag, /* the CommandTag */
+ plantree_list, /* List of PlannedStmt* */
+ NULL /* no CachedPlan */
+ );
+#endif
```
### Adapt ExecInitRangeTable() calls to PG-18’s new signature
PostgreSQL commit
[cbc127917e04a978a788b8bc9d35a70244396d5b](cbc127917e)
overhauled the planner API for range‐table initialization:
**PG 18+**: added a fourth `Bitmapset *unpruned_relids` argument to
support deferred partition pruning
In Citus’s `create_estate_for_relation()` (in `columnar_metadata.c`), we
now wrap the call in a compile‐time guard so that the code compiles
correctly on all supported PostgreSQL versions:
```
/* Prepare permission info on PG 16+ */
#if PG_VERSION_NUM >= PG_VERSION_16
List *perminfos = NIL;
addRTEPermissionInfo(&perminfos, rte);
#else
List *perminfos = NIL; /* unused on PG 15 */
#endif
/* Initialize the range table, with the right signature for each PG version */
#if PG_VERSION_NUM >= PG_VERSION_18
/* PG 18+: four‐arg signature (adds unpruned_relids) */
ExecInitRangeTable(
estate,
list_make1(rte),
perminfos,
NULL /* unpruned_relids: not used by columnar */
);
#elif PG_VERSION_NUM >= PG_VERSION_16
/* PG 16–17: three‐arg signature (permInfos) */
ExecInitRangeTable(
estate,
list_make1(rte),
perminfos
);
#else
/* PG 15: two‐arg signature */
ExecInitRangeTable(
estate,
list_make1(rte)
);
#endif
estate->es_output_cid = GetCurrentCommandId(true);
```
### Adapt `pgstat_report_vacuum()` to PG-18’s new timestamp argument
PostgreSQL commit
[[30a6ed0ce4bb18212ec38cdb537ea4b43bc99b83](30a6ed0ce4)
extended the `pgstat_report_vacuum()` API by adding a `TimestampTz
start_time` parameter at the end so that the VACUUM statistics collector
can record when the operation began:
```diff
/* PG ≤17: four-arg signature */
- void pgstat_report_vacuum(Oid tableoid,
- bool shared,
- double num_live_tuples,
- double num_dead_tuples);
+/* PG ≥18: five-arg signature adds a start_time */
+ void pgstat_report_vacuum(Oid tableoid,
+ bool shared,
+ double num_live_tuples,
+ double num_dead_tuples,
+ TimestampTz start_time);
```
To support both versions, we now wrap the call in `columnar_tableam.c`
with a version guard, supplying `GetCurrentTimestamp()` for PG-18+:
```c
#if PG_VERSION_NUM >= 180000
/* PG 18+: include start_timestamp */
pgstat_report_vacuum(
RelationGetRelid(rel),
rel->rd_rel->relisshared,
Max(new_live_tuples, 0), /* live tuples */
0, /* dead tuples */
GetCurrentTimestamp() /* start time */
);
#else
/* PG 15–17: original signature */
pgstat_report_vacuum(
RelationGetRelid(rel),
rel->rd_rel->relisshared,
Max(new_live_tuples, 0), /* live tuples */
0 /* dead tuples */
);
#endif
```
### Adapt `ExecuteTaskPlan()` to PG-18’s expanded `CreateQueryDesc()`
signature
PostgreSQL 18 changed `CreateQueryDesc()` from an eight-argument to a
nine-argument call by inserting a `CachedPlan *cplan` parameter
immediately after the `PlannedStmt *plannedstmt` argument (see commit
525392d572).
To remain compatible with PG 15–17, Citus now wraps its invocation in
`local_executor.c` with a version guard:
```diff
- /* PG15–17: eight-arg CreateQueryDesc without cached plan */
- QueryDesc *queryDesc = CreateQueryDesc(
- taskPlan, /* PlannedStmt *plannedstmt */
- queryString, /* const char *sourceText */
- GetActiveSnapshot(),/* Snapshot snapshot */
- InvalidSnapshot, /* Snapshot crosscheck_snapshot */
- destReceiver, /* DestReceiver *dest */
- paramListInfo, /* ParamListInfo params */
- queryEnv, /* QueryEnvironment *queryEnv */
- 0 /* int instrument_options */
- );
+#if PG_VERSION_NUM >= 180000
+ /* PG18+: nine-arg CreateQueryDesc with a CachedPlan slot */
+ QueryDesc *queryDesc = CreateQueryDesc(
+ taskPlan, /* PlannedStmt *plannedstmt */
+ NULL, /* CachedPlan *cplan (none) */
+ queryString, /* const char *sourceText */
+ GetActiveSnapshot(),/* Snapshot snapshot */
+ InvalidSnapshot, /* Snapshot crosscheck_snapshot */
+ destReceiver, /* DestReceiver *dest */
+ paramListInfo, /* ParamListInfo params */
+ queryEnv, /* QueryEnvironment *queryEnv */
+ 0 /* int instrument_options */
+ );
+#else
+ /* PG15–17: eight-arg CreateQueryDesc without cached plan */
+ QueryDesc *queryDesc = CreateQueryDesc(
+ taskPlan, /* PlannedStmt *plannedstmt */
+ queryString, /* const char *sourceText */
+ GetActiveSnapshot(),/* Snapshot snapshot */
+ InvalidSnapshot, /* Snapshot crosscheck_snapshot */
+ destReceiver, /* DestReceiver *dest */
+ paramListInfo, /* ParamListInfo params */
+ queryEnv, /* QueryEnvironment *queryEnv */
+ 0 /* int instrument_options */
+ );
+#endif
```
### Adapt `RelationGetPrimaryKeyIndex()` to PG-18’s new “deferrable\_ok”
flag
PostgreSQL commit
14e87ffa5c
added a new Boolean `deferrable_ok` parameter to
`RelationGetPrimaryKeyIndex()` so that the lock manager can defer
unique‐constraint locks when requested. The API changed from:
```c
RelationGetPrimaryKeyIndex(Relation relation)
```
to:
```c
RelationGetPrimaryKeyIndex(Relation relation, bool deferrable_ok)
```
```diff

Because Citus has always taken the lock immediately—just as the old
two-arg call did—we pass `false` to keep that same immediate-lock
behavior. Passing `true` would switch to deferred locking, which we
don’t want.
### Adapt `ExplainOnePlan()` to PG-18’s expanded API
PostgreSQL 18 extended
525392d572
the `ExplainOnePlan()` function to carry the `CachedPlan *` and
`CachedPlanSource *` pointers plus an explicit `query_index`, letting
the EXPLAIN machinery track plan‐source invalidation. The old signature:
```c
/* PG ≤17 */
void
ExplainOnePlan(PlannedStmt *plannedstmt,
IntoClause *into,
struct ExplainState *es,
const char *queryString,
ParamListInfo params,
QueryEnvironment *queryEnv,
const instr_time *planduration,
const BufferUsage *bufusage);
```
became, in PG 18:
```c
/* PG ≥18 */
void
ExplainOnePlan(PlannedStmt *plannedstmt,
CachedPlan *cplan,
CachedPlanSource *plansource,
int query_index,
IntoClause *into,
struct ExplainState *es,
const char *queryString,
ParamListInfo params,
QueryEnvironment *queryEnv,
const instr_time *planduration,
const BufferUsage *bufusage,
const MemoryContextCounters *mem_counters);
```
To compile under both versions, Citus now wraps each call in
`multi_explain.c` with:
```c
#if PG_VERSION_NUM >= PG_VERSION_18
/* PG 18+: pass NULL for the new cached‐plan fields and zero for query_index */
ExplainOnePlan(
plan, /* PlannedStmt *plannedstmt */
NULL, /* CachedPlan *cplan */
NULL, /* CachedPlanSource *plansource */
0, /* query_index */
into, /* IntoClause *into */
es, /* ExplainState *es */
queryString, /* const char *queryString */
params, /* ParamListInfo params */
NULL, /* QueryEnvironment *queryEnv */
&planduration,/* const instr_time *planduration */
(es->buffers ? &bufusage : NULL),
(es->memory ? &mem_counters : NULL)
);
#elif PG_VERSION_NUM >= PG_VERSION_17
/* PG 17: same as before, plus passing mem_counters if enabled */
ExplainOnePlan(
plan,
into,
es,
queryString,
params,
queryEnv,
&planduration,
(es->buffers ? &bufusage : NULL),
(es->memory ? &mem_counters : NULL)
);
#else
/* PG 15–16: original seven-arg form */
ExplainOnePlan(
plan,
into,
es,
queryString,
params,
queryEnv,
&planduration,
(es->buffers ? &bufusage : NULL)
);
#endif
```
### Adapt to the unified “index interpretation” API in PG 18 (commit
a8025f544854)
PostgreSQL commit
a8025f5448
generalized the old btree‐specific operator‐interpretation API into a
single “index interpretation” interface:
* **Renamed type**:
`OpBtreeInterpretation` → `OpIndexInterpretation`
* **Renamed function**:
`get_op_btree_interpretation(opno)` →
`get_op_index_interpretation(opno)`
* **Unified field**:
Each interpretation now carries `cmptype` instead of `strategy`.
To build cleanly on PG 18 while still supporting PG 15–17, Citus’s
shard‐pruning code now wraps these changes:
```c
#include "pg_version_constants.h"
#if PG_VERSION_NUM >= PG_VERSION_18
/* On PG 18+ the btree‐only APIs vanished; alias them to the new generic versions */
typedef OpIndexInterpretation OpBtreeInterpretation;
#define get_op_btree_interpretation(opno) get_op_index_interpretation(opno)
#define ROWCOMPARE_NE COMPARE_NE
#endif
/* … later, when checking an interpretation … */
OpBtreeInterpretation *interp =
(OpBtreeInterpretation *) lfirst(cell);
#if PG_VERSION_NUM >= PG_VERSION_18
/* use cmptype on PG 18+ */
if (interp->cmptype == ROWCOMPARE_NE)
#else
/* use strategy on PG 15–17 */
if (interp->strategy == ROWCOMPARE_NE)
#endif
{
/* … */
}
```
### Adapt `create_foreignscan_path()` for PG-18’s revised signature
PostgreSQL commit
e222534679
reordered and removed a couple of parameters in the FDW‐path builder:
* **PG 15–17 signature (11 args)**
```c
create_foreignscan_path(PlannerInfo *root,
RelOptInfo *rel,
PathTarget *target,
double rows,
Cost startup_cost,
Cost total_cost,
List *pathkeys,
Relids required_outer,
Path *fdw_outerpath,
List *fdw_restrictinfo,
List *fdw_private);
```
* **PG 18+ signature (9 args)**
```c
create_foreignscan_path(PlannerInfo *root,
RelOptInfo *rel,
PathTarget *target,
double rows,
int disabled_nodes,
Cost startup_cost,
Cost total_cost,
Relids required_outer,
Path *fdw_outerpath,
List *fdw_private);
```
To support both, Citus now defines a compatibility macro in
`pg_version_compat.h`:
```c
#include "nodes/bitmapset.h" /* for Relids */
#include "nodes/pg_list.h" /* for List */
#include "optimizer/pathnode.h" /* for create_foreignscan_path() */
#if PG_VERSION_NUM >= PG_VERSION_18
/* PG18+: drop pathkeys & fdw_restrictinfo, add disabled_nodes */
#define create_foreignscan_path_compat(a, b, c, d, e, f, g, h, i, j, k) \
create_foreignscan_path( \
(a), /* root */ \
(b), /* rel */ \
(c), /* target */ \
(d), /* rows */ \
(0), /* disabled_nodes (unused by Citus) */ \
(e), /* startup_cost */ \
(f), /* total_cost */ \
(g), /* required_outer */ \
(h), /* fdw_outerpath */ \
(k) /* fdw_private */ \
)
#else
/* PG15–17: original signature */
#define create_foreignscan_path_compat(a, b, c, d, e, f, g, h, i, j, k) \
create_foreignscan_path( \
(a), (b), (c), (d), \
(e), (f), \
(g), (h), (i), (j), (k) \
)
#endif
```
Now every call to `create_foreignscan_path_compat(...)`—even in tests
like `fake_fdw.c`—automatically picks the correct argument list for
PG 15 through PG 18.
### Drop the obsolete bitmap‐scan hooks on PG 18+
PostgreSQL commit
c3953226a0
cleaned up the `TableAmRoutine` API by removing the two bitmap‐scan
callback slots:
* `scan_bitmap_next_block`
* `scan_bitmap_next_tuple`
Since those hook‐slots no longer exist in PG 18, Citus now wraps their
NULL‐initialization in a `#if PG_VERSION_NUM < PG_VERSION_18` guard. On
PG 15–17 we still explicitly set them to `NULL` (to satisfy the old
struct layout), and on PG 18+ we omit them entirely:
```c
#if PG_VERSION_NUM < PG_VERSION_18
/* PG 15–17 only: these fields were removed upstream in PG 18 */
.scan_bitmap_next_block = NULL,
.scan_bitmap_next_tuple = NULL,
#endif
```
### Adapt `vac_update_relstats()` invocation to PG-18’s new
“all\_frozen” argument
PostgreSQL commit
99f8f3fbbc
extended the `vac_update_relstats()` API by inserting a
`num_all_frozen_pages` parameter between the existing
`num_all_visible_pages` and `hasindex` arguments:
```diff
- /* PG ≤17: */
- void
- vac_update_relstats(Relation relation,
- BlockNumber num_pages,
- double num_tuples,
- BlockNumber num_all_visible_pages,
- bool hasindex,
- TransactionId frozenxid,
- MultiXactId minmulti,
- bool *frozenxid_updated,
- bool *minmulti_updated,
- bool in_outer_xact);
+ /* PG ≥18: adds num_all_frozen_pages */
+ void
+ vac_update_relstats(Relation relation,
+ BlockNumber num_pages,
+ double num_tuples,
+ BlockNumber num_all_visible_pages,
+ BlockNumber num_all_frozen_pages,
+ bool hasindex,
+ TransactionId frozenxid,
+ MultiXactId minmulti,
+ bool *frozenxid_updated,
+ bool *minmulti_updated,
+ bool in_outer_xact);
```
To compile cleanly on both PG 15–17 and PG 18+, Citus wraps its call in
a version guard and supplies a zero placeholder for the new field:
```c
#if PG_VERSION_NUM >= 180000
/* PG 18+: supply explicit “all_frozen” count */
vac_update_relstats(
rel,
new_rel_pages,
new_live_tuples,
new_rel_allvisible, /* allvisible */
0, /* all_frozen */
nindexes > 0,
newRelFrozenXid,
newRelminMxid,
&frozenxid_updated,
&minmulti_updated,
false /* in_outer_xact */
);
#else
/* PG 15–17: original signature */
vac_update_relstats(
rel,
new_rel_pages,
new_live_tuples,
new_rel_allvisible,
nindexes > 0,
newRelFrozenXid,
newRelminMxid,
&frozenxid_updated,
&minmulti_updated,
false /* in_outer_xact */
);
#endif
```
**Why all_frozen = 0?**
Columnar storage never embeds transaction IDs in its pages, so it never
needs to track “all‐frozen” pages the way a heap does. Setting both
allvisible and allfrozen to zero simply tells Postgres “there are no
pages with the visibility or frozen‐status bits set,” matching our
existing behavior.
This change ensures Citus’s VACUUM‐statistic updates work unmodified
across all supported Postgres versions.
DESCRIPTION: Drops PG14 support
1. Remove "$version_num" != 'xx' from configure file
2. delete all PG_VERSION_NUM = PG_VERSION_XX references in the code
3. Look at pg_version_compat.h file, remove all _compat functions etc
defined specifically for PGXX differences
4. delete all PG_VERSION_NUM >= PG_VERSION_(XX+1), PG_VERSION_NUM <
PG_VERSION_(XX+1) ifs in the codebase
5. delete ruleutils_xx.c file
6. cleanup normalize.sed file from pg14 specific lines
7. delete all alternative output files for that particular PG version,
server_version_ge variable helps here
This PR provides successful compilation against PG17.0.

- Simplify CitusNewNode (#7434)
postgres refactored newNode() in PG 17, the main point for doing this is
the original tricks is no longer neccessary for modern compilers[1].
This does the same for Citus.
This should have no backward compatibility issues since it just replaces
palloc0fast with palloc0.
This is good for forward compatibility since palloc0fast no longer
exists in PG 17.

(cherry picked from commit 4b295cc)
This change adds a script to programatically group all includes in a
specific order. The script was used as a one time invocation to group
and sort all includes throught our formatted code. The grouping is as
follows:
- System includes (eg. `#include<...>`)
- Postgres.h (eg. `#include "postgres.h"`)
- Toplevel imports from postgres, not contained in a directory (eg.
`#include "miscadmin.h"`)
- General postgres includes (eg . `#include "nodes/..."`)
- Toplevel citus includes, not contained in a directory (eg. `#include
"citus_verion.h"`)
- Columnar includes (eg. `#include "columnar/..."`)
- Distributed includes (eg. `#include "distributed/..."`)
Because it is quite hard to understand the difference between toplevel
citus includes and toplevel postgres includes it hardcodes the list of
toplevel citus includes. In the same manner it assumes anything not
prefixed with `columnar/` or `distributed/` as a postgres include.
The sorting/grouping is enforced by CI. Since we do so with our own
script there are not changes required in our uncrustify configuration.
This PR provides successful compilation against PG16Beta2. It does some
necessary refactoring to prepare for full support of version 16, in
https://github.com/citusdata/citus/pull/6952 .

Pass NULL context to stringToQualifiedNameList, typeStringToTypeName
The pre-PG16 error behaviour for the following
stringToQualifiedNameList & typeStringToTypeName
was ereport(ERROR, ...)
Now with PG16 we have this context input. We preserve the same behaviour
by passing a NULL context, because of the following:
(copy paste comment from PG16)
If "context" isn't an ErrorSaveContext node, this behaves as
errstart(ERROR, domain), and the errsave() macro ends up acting
exactly like ereport(ERROR, ...).

This commit is the second and last phase of dropping PG13 support.
It consists of the following:
- Removes all PG_VERSION_13 & PG_VERSION_14 from codepaths
- Removes pg_version_compat entries and columnar_version_compat entries
specific for PG13
- Removes alternative pg13 test outputs
- Removes PG13 normalize lines and fix the test outputs based on that
It is a continuation of 5bf163a27d
