Subject: pgsql: doc: Update outdated descriptions of wal_status in pg_replicatio
Date: Thu, 03 Jul 2025 14:10:44 +0000
Message-ID: <E1uXKeC-004WgS-1m@gemulon.postgresql.org> (raw)
doc: Update outdated descriptions of wal_status in pg_replication_slots.
The documentation for pg_replication_slots previously mentioned only
max_slot_wal_keep_size as a condition under which the wal_status column
could show unreserved or lost. However, since commit be87200,
replication slots can also be invalidated due to horizon or wal_level,
and since commit ac0e33136ab, idle_replication_slot_timeout can also
trigger this state.
This commit updates the description of the wal_status column to
reflect that max_slot_wal_keep_size is not the only cause of the lost state.
Back-patched to v16, where the additional invalidation cases were introduced.
