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, ...).

DESCRIPTION: Raises memory limits in columnar from 256MB to 1GB for
reads and writes
This doesn't completely fix#5918 but at least increases the
buffer limits that might cause throwing an error when reading
from or writing into into columnar storage. A way better approach
to fix this is documented in #6420.
Replacing memcpy_s with memcpy is quite safe in those places
since we anyway make sure to allocate enough amount of memory
before writing into related buffers.
Previously, we were doing `first_row_number` reservation for the first
row written to current `WriteState` but were doing `stripe_id`
reservation when flushing the `WriteState` and were inserting the
related record to `columnar.stripe` at that time as well.
However, inserting `columnar.stripe` record at flush-time is
problematic. This is because, as told in #5160, if relation has
any index-based constraints and if there are two concurrent
writes that are inserting conflicting key values for that constraint,
then postgres relies on `tableAM->fetch_index_tuple`
(=`columnar_fetch_index_tuple`) callback to return `true` when
indexAM is checking against possible constraint violations.
However, pending writes of other backends are not visible to concurrent
sessions in columnar since we were not inserting the stripe metadata
record until flushing the stripe.
With this commit, we split stripe reservation into two phases:
i) Reserve `stripe_id` and insert a "dummy" record to `columnar.stripe`
at the very same time we reserve `first_row_number`, i.e. when writing
the first row to the current `WriteState`.
ii) At flush time, do the storage level allocation and complete the
missing fields of the dummy record inserted into `columnar.stripe`
during i).
That way, any concurrent writes would be able to check against possible
constraint violations by using `SnapshotDirty` when scanning
`columnar.stripe`.
Note that `columnar_fetch_index_tuple` still wouldn't be able to fill
the output tupleslot for the requested tid but it would at least return
`true` for such index look-up's and we believe this should be sufficient
for the caller indexAM callback to make the concurrent writer block on
prior one.
That is how we fix#5160.
Only downside of reserving `stripe_id` at the same time we reserve
`first_row_number` is that now any aborted writes would also waste
some amount of `stripe_id` as in the case of `first_row_number` but
we are just wasting them one-by-one.
Considering the fact that we waste `first_row_number` by the amount
stripe row limit (=150k by default) in such cases, this shouldn't be
important at all.
* Columnar: introduce columnar storage API.
This new API is responsible for the low-level storage details of
columnar; translating large reads and writes into individual block
reads and writes that respect the page headers and emit WAL. It's also
responsible for the columnar metapage, resource reservations (stripe
IDs, row numbers, and data), and truncation.
This new API is not used yet, but will be used in subsequent
forthcoming commits.
* Columnar: add columnar_storage_info() for debugging purposes.
* Columnar: expose ColumnarMetadataNewStorageId().
* Columnar: always initialize metapage at creation time.
This avoids the complexity of dealing with tables where the metapage
has not yet been initialized.
* Columnar: columnar storage upgrade/downgrade UDFs.
Necessary upgrade/downgrade step so that new code doesn't see an old
metapage.
* Columnar: improve metadata.c comment.
* Columnar: make ColumnarMetapage internal to the storage API.
Callers should not have or need direct access to the metapage.
* Columnar: perform resource reservation using storage API.
* Columnar: implement truncate using storage API.
* Columnar: implement read/write paths with storage API.
* Columnar: add storage tests.
* Revert "Columnar: don't include stripe reservation locks in lock graph."
This reverts commit c3dcd6b9f8.
No longer needed because the columnar storage API takes care of
concurrency for resource reservation.
* Columnar: remove unnecessary lock when reserving.
No longer necessary because the columnar storage API takes care of
concurrent resource reservation.
* Add simple upgrade tests for storage/ branch
* fix multi_extension.out
