Subject: pgsql: Add num_done counter to the pg_stat_checkpointer view.
Date: Mon, 30 Sep 2024 03:15:52 +0000
Message-ID: <E1sv6t5-001VuH-JQ@gemulon.postgresql.org> (raw)
Add num_done counter to the pg_stat_checkpointer view.
Checkpoints can be skipped when the server is idle. The existing num_timed and
num_requested counters in pg_stat_checkpointer track both completed and
skipped checkpoints, but there was no way to count only the completed ones.
This commit introduces the num_done counter, which tracks only completed
checkpoints, making it easier to see how many were actually performed.
Bump catalog version.
