Historically, Yugabyte merged the following upstream PG commits - YB 984667e: PG ab5e9caa4a3ec4765348a0482e88edcf3f6aab4a (tag: REL_10_4) - YB cb4bd4c: PG 6cd404b344f7e27f4d64555bb133f18a758fe851 (tag: REL_11_2) This commit is the start of the third merge: PG 78ec02d612a9b69039ec2610740f738968fe144d (tag: REL_15_2). The initial merge was a series of commits primarily authored by neil. I, jason, squash those commits together into this one because his individual commits were authored in a way that makes the history hard to read. I also use YugaBot as the official author/committer as that is how it's historically done. I leave the original commit messages below as reference. commit a6974e5 Author: neil <nocaway@users.noreply.github.com> AuthorDate: Wed Oct 26 15:54:10 2022 -0700 Commit: neil <nocaway@users.noreply.github.com> CommitDate: Thu Jul 20 02:08:22 2023 -0700 Merge with some of Postgres 15 Summary: Merge with PG13 Test Plan: None Suppressed compiling Postgres's extension.

In the past, there were 2 subcommands involved when creating a primary key: 1) `AddIndex` 2) `SetNotNull` (only if any one of the primary key attributes are not set as NOT NULL). In PG13, setting the primary key columns to NOT NULL is triggered in a separate API called `transformIndexConstraint`. The boolean flag has been set in the corresponding section where `AlterTableCmd` is prepared to alter the primary key column to be not null. Here is the excerpt from the PG13 comment mentioning the need to satisfy NOT NULL requirement prior to creating primary key index: ```Now we expect that the parser inserted any required ALTER TABLE SET NOT NULL operations before trying to create a primary-key index.``` Test Plan: Jenkins Reviewers: neil, myang Reviewed By: myang Subscribers: yql Differential Revision: https://phabricator.dev.yugabyte.com/D21331 commit 85d6668 Author: Jason Kim <git@jasonk.me> AuthorDate: Fri Jan 27 12:11:07 2023 -0800 Commit: neil <nocaway@users.noreply.github.com> CommitDate: Thu Jul 20 02:08:22 2023 -0700 [MERGE PG13] ysql: fix some compilation errors Summary: Fix two compilation errors: - release build got -Wsometimes-uninitialized compilation error because of Assert(false) that is treated differently in release/debug builds - gcc build got -Werror=comment because of bad comment Test Plan: Jenkins: compile only, rebase: pg13 ./yb_build.sh fastdebug --gcc11 --no-initdb ./yb_build.sh release --clang15 --no-initdb Reviewers: smishra, neil Reviewed By: neil Subscribers: yql Differential Revision: https://phabricator.dev.yugabyte.com/D22577 commit b15ae1e Author: Fizaa Luthra <fizaaluthra@gmail.com> AuthorDate: Thu Feb 2 11:58:29 2023 -0500 Commit: neil <nocaway@users.noreply.github.com> CommitDate: Thu Jul 20 02:08:23 2023 -0700 [MERGE PG13][#14506] Fix YbClearCurrentTransactionId() Summary: YbClearCurrentTransactionId() was introduced to handle temp tables created during concurrent materialized view refreshes correctly. PG13 no longer uses `CurrentTransactionState->transactionId` and `MyPgXact`. This diff changes the code to use the PG13 equivalent of these fields/structures - `CurrentTransactionState->fullTransactionId` and `MyProc->xid`.

This change localizes the use of pattern_fixed_prefix() and make_greater_string() so that they no longer need be exported. (We might get pushback from extensions about that, perhaps, in which case I'd be inclined to re-export them in a new header file like_support.h.) ... ybgin uses make_greater_string for tsvector prefix logic. Since it is not trivial to indirectly get the benefit of make_greater_string through the publicly exposed support functions (they take complex Node argument), lean towards re-exposing the function through new header yb_like_support.h and new function yb_make_greater_string. If, in the future, upstream postgres decides to expose make_greater_string, these changes can be scrapped in favor of using make_greater_string again.

This is what jenkins runs, whereas developers typically run ./yb_build.sh. doctest appears to have a strange bug where it does not like it when sys.stdout is set to something else by the time of the end of file. This doesn't seem to matter when executing the python script itself: it only matters for doctest. PG 15 merge involves updating generate_unaccent_rules.py, and this update hits the above bug. Appease doctest by restoring sys.stdout to the original object at the end of the file. It seems wasteful to run doctest on files that don't have docstrings, but that can be fixed in the future.

It overwrites the variable with the same name in the outer scope, defined for the chunk. However, in PG upstream, the `oldsize` in the outer scope is referenced in the inner scope. Because of the naming overwritting, after merging, the reference used becomes incorrect. **Solution** I basically "backport" how the upstream creates the variable for "block old size" and use it is for YB memory tracking. Along with this, it also fixes two potential overflow issues in the existing code. The fixes are needed in the master as well. So a backport to the PG13 branch will be committed later in a separate diff.
