Don't reset 'latest_page_number' when replaying multixid truncation
'latest_page_number' is set to the correct value, according to
nextOffset, early at system startup. Contrary to the comment, it hence
should be set up correctly by the time we get to WAL replay.
This was committed to back-branche
Remove nonfunctional tar file trailer size check.
The ASTREAMER_ARCHIVE_TRAILER case in astreamer_tar_parser_content()
intended to reject tar files whose trailer exceeded 2 blocks. However,
the check compared 'len' after astreamer_buffer_bytes() had already
consumed all the data and set len to 0,
Fix assorted bugs in archive_waldump.c.
1. archive_waldump.c called astreamer_finalize() nowhere. This meant
that any data retained in decompression buffers at the moment we
detect archive EOF would never reach astreamer_waldump_content(),
resulting in surprising failures if we actually need the
Fix another buglet in archive_waldump.c.
While re-reading 860359ea0, I noticed another problem: when
spilling to a temp file, it did not bother to check the result
of fclose(). This is bad since write errors (like ENOSPC)
may not be reported until close time.

Add fake LSN support to hash index AM.
Use fake LSNs in all hash AM critical sections that write a WAL record.
This gives us a reliable way (a way that works during scans of both
logged and unlogged relations) to detect when an index page was
concurrently modified during the window between when th

Detect and fix visibility map corruption in more cases
Move VM corruption detection and repair into heap page pruning. This
allows VM repair during on-access pruning, not only during vacuum.
Also, expand corruption detection to cover pages marked all-visible that
contain dead tuples and tuples in
Make IndexScanInstrumentation a pointer in executor scan nodes.
Change the IndexScanInstrumentation fields in IndexScanState,
IndexOnlyScanState, and BitmapIndexScanState from inline structs to
pointers. This avoids additional space overhead whenever new fields are
added to IndexScanInstrumentati
Add pruning fast path for all-visible and all-frozen pages
Because of the SKIP_PAGES_THRESHOLD optimization or a stale prune XID,
heap_page_prune_and_freeze() can be invoked for pages with no pruning or

it is all-visible and no
Add missing deflateEnd() for server-side gzip base backups
The gzip basebackup sink called deflateInit2() in begin_archive() but
never called deflateEnd(), leaking zlib's internal compression state
(~256KB per archive) until the memory context of the base backup is
destroyed.
