Subject: pgsql: Check that a promoted standby keeps its 8-byte OID counter
Date: Mon, 14 Sep 2026 03:07:38 +0000
Message-ID: <E1x5x2g-00000000DvO-1US6@gemulon.postgresql.org> (raw)
Check that a promoted standby keeps its 8-byte OID counter
The counter reaches a standby through XLOG_NEXTOID and checkpoint
records. This commit adds a test to move the next OID past the 2^32
limit on a primary and read it back from the promoted standby. This
reuses the same trick as some of the previous tests, with a pg_resetwal
command setting the next OID to be larger than 2^32, combined with a
check based on pg_control_checkpoint().
This closes a testing gap of cb298616463d regarding the replay of
XLOG_NEXTOID, where this WAL record has been updated to pass down an
Oid8 value. By default, regression tests would use OIDs way below the
UINT32_MAX limit.
