Citus build with PG16 fails because of the following warnings:
- using char* instead of Datum
- using pointer instead of oid
- candidate function for format attribute
- remove old definition from PG11 compatibility 62bf571ced
This commit fixes the above.
This PR makes all of the features open source that were previously only
available in Citus Enterprise.
Features that this adds:
1. Non blocking shard moves/shard rebalancer
(`citus.logical_replication_timeout`)
2. Propagation of CREATE/DROP/ALTER ROLE statements
3. Propagation of GRANT statements
4. Propagation of CLUSTER statements
5. Propagation of ALTER DATABASE ... OWNER TO ...
6. Optimization for COPY when loading JSON to avoid double parsing of
the JSON object (`citus.skip_jsonb_validation_in_copy`)
7. Support for row level security
8. Support for `pg_dist_authinfo`, which allows storing different
authentication options for different users, e.g. you can store
passwords or certificates here.
9. Support for `pg_dist_poolinfo`, which allows using connection poolers
in between coordinator and workers
10. Tracking distributed query execution times using
citus_stat_statements (`citus.stat_statements_max`,
`citus.stat_statements_purge_interval`,
`citus.stat_statements_track`). This is disabled by default.
11. Blocking tenant_isolation
12. Support for `sslkey` and `sslcert` in `citus.node_conninfo`
PostgreSQL does not need calling this function since 7.4 release, and it
is a NOOP.

tuplestore_donestoring() isn't needed anymore, but provide a no-op
macro definition so as not to create compatibility problems.

Previously this was usually done after argument parsing. This can cause
SEGFAULTs if the number or type of arguments changes in a new version.
By checking that Citus version is correct before doing any argument
parsing we protect against these types of issues. Issues like this have
occurred in pg_auto_failover, so it's not just a theoretical issue.
The main reason why these calls were not at the top of functions is
really just historical. It was because in the past we didn't allow
statements before declarations. Thus having this check before the
argument parsing would have only been possible if we first declared all
variables.
In addition to moving existing CheckCitusVersion calls it also adds
these calls to rebalancer related functions (they were missing there).
On top of our foreign key graph, implement the infrastructure to get
list of relations that are connected to input relation via a foreign key
graph.
We need this to support cascading create_citus_local_table &
undistribute_table operations.
Also add regression tests to see what our foreign key graph is able to
capture currently.
This commit mostly adds pg_get_triggerdef_command to our ruleutils_13.
This doesn't add anything extra for ruleutils 13 so it is basically a copy
of the change on ruleutils_12
Pass the list to lnext API
lnext API now expects the list as well.
The commit on Postgres that introduced the change: 1cff1b95ab6ddae32faa3efe0d95a820dbfdc164
lnext_compat and list_delete_cell_compat macros are introduced so that
we can use these macros in the codebase without having to use #if
directives in the codebase.

Command to search in postgres:
git log --all --grep="list_delete_cell"
add ListCellAndListWrapper
When iterating a list in separate function calls, we need both the list
and the current cell starting from PG13, therefore
ListCellAndListWrapper is added to store both as a wrapper.
Use ListCellAndListWrapper in foreign key test udfs
As we iterate a list in these udfs using a functionContext, we need to
use the wrapper to be able to access both the list and the current cell.
This copies over fixes from reference counting branch,
all CitusTableCacheEntry data may be freed when a GetCitusTableCacheEntry call occurs for its relationId
This fix is not complete, but reference counting is being deferred until 9.4
CopyShardInterval: remove dest parameter, always return newly allocated object
