I think this is okay, with the caveat that we'd be changing the behavior (again) in a future release, rather than doing it all in v14. Maybe the behavior should be documented, though. Actually, I thought the pre-existing (non)behavior of autoanalyze would've been documented, and we'd now update that. All I can find is this: https://www.postgresql.org/docs/current/sql-analyze.html |The autovacuum daemon, however, will only consider inserts or updates on the |parent table itself when deciding whether to trigger an automatic analyze for |that table I think that should probably have been written down somewhere other than for the manual ANALYZE command, but in any case it seems to be outdated now. -- Justin
