Coordinate emit_log_hook and all log destinations to share the same timeval
This would cause the timestamp values used by emit_log_hook and all the
other log destinations to differ, because the timestamps are reset
before sending the logs to the server and after calling the hook.

Preliminary refactor of heap scanning functions
To allow the use of the read stream API added in b5a9b18cd for
sequential scans on heap tables, here we make some adjustments to make
that change less invasive and perhaps make the code easier to follow in
the process.
Here heapgetpage() gets broken
pg_regress: Save errno in emit_tap_output_v() and switch to %m
emit_tap_output_v() includes some fprintf() calls for some output
related to the TAP protocol, that may clobber errno and break %m. This
commit makes the logging of pg_regress smarter by saving errno before
restoring it in vfprintf()
CREATE INDEX: do not update stats during binary upgrade.
During binary upgrade, indexes are created before the data is moved
into place, so it will always be zero.
This is not currently a major problem, but will be when we try to
preserve statistics during upgrade.

Invent SERIALIZE option for EXPLAIN.
EXPLAIN (ANALYZE, SERIALIZE) allows collection of statistics about

to convert the data to the on-the-wire format. Previously there

docs: Demote "Monitoring Disk Usage" from chapter to section.
This chapter is very short, and the immediately preceding chapter is
called "Monitoring Database Activity". So, instead of having a

Split XLogCtl->LogwrtResult into separate struct members
After this change we have XLogCtl->logWriteResult and ->logFlushResult.
There's no functional change, other than the fact that the assignment
from shared memory to local is no longer done via struct assignment, but
instead using a macro that
Inline pg_popcount() for small buffers.
If there aren't many bytes to process, the function call overhead
of the optimized implementation isn't worth taking, so instead we

Combine freezing and pruning steps in VACUUM
Execute both freezing and pruning of tuples in the same
heap_page_prune() function, now called heap_page_prune_and_freeze(),
and emit a single WAL record containing all changes. That reduces the
overall amount of WAL generated.
This moves the freezing
Refactor how heap_prune_chain() updates prunable_xid
In preparation of freezing and counting tuples which are not
candidates for pruning, split heap_prune_record_unchanged() into
multiple functions, depending the kind of line pointer. That's not too
interesting right now, but makes the next commit
Fix zeroing of pg_serial page without SLRU bank lock
Bug in commit 53c2a97a9266: we failed to acquire the correct SLRU bank

Use the pairing heap instead of a flat array for LSN replay waiters

the particular LSN to be replayed on standby. The waiters were stored in

Argh, sorry. I think someone else fixed this.

Drop global objects after completed test
Project policy is to not leave global objects behind after a regress
test run. This was found as a result of the development of a patch
to make pg_regress detect such leftovers automatically, which in the
end was withdrawn due to issues with parallel runs.

Ensure that the sync slots reach a consistent state after promotion without
losing data.
We were directly copying the LSN locations while syncing the slots on the
standby. Now, it is possible that at some particular restart_lsn there are
some running xacts, which means if we start reading the WAL
