Re: [PATCH] Improving Visibility of Temporary Table Usage

Hi hackers,

Here is v2 of this patch, rebased on current HEAD (cae90d74796, as of
2026-06-25).

This rebase was triggered by the CFBot "Needs rebase" notification on CommitFest
entry #6835 [1]. The patch no longer applied cleanly due to upstream's async I/O
refactor

[1] https://commitfest.postgresql.org/patch/6835/

Changes from v1:
- Rebased onto PostgreSQL 19beta1 HEAD (1047 commits upstream since v1)
- Adapted bufmgr.c changes to work with the async I/O refactor introduced
upstream. pgstat_count_local_blk_hit() is now placed inside TrackBufferHit(),
the unified hit-tracking function added by the async I/O work.
pgstat_count_local_blk_read() is placed in StartReadBuffersImpl() next to
the existing local_blks_read update.
- Added missing !OidIsValid(dboid) || !IsUnderPostmaster guards to
pgstat_count_temp_table() for consistency with the other 4 counting
functions added in the same patch.
- Added !IsBootstrapProcessingMode() check in heap.c (defensive; bootstrap
cannot create temp tables, but makes intent explicit).

Patch attached.
