Subject: pgsql: Fix limit block handling in pg_wal_summary_contents().
Date: Tue, 09 Jul 2024 00:30:29 +0000
Message-ID: <E1sQykX-000v7C-Ff@gemulon.postgresql.org> (raw)
Fix limit block handling in pg_wal_summary_contents().
Previously, pg_wal_summary_contents() had two issues,
causing discrepancies between pg_wal_summary_contents()
and the pg_walsummary command on the same WAL summary file:
(1) It did not emit the limit block when that's the only data for
a particular relation fork.
(2) It emitted the same limit block multiple times if the list of
block numbers was long enough.
This commit fixes these issues.
Backpatch to v17 where pg_wal_summary_contents() was added.
