Subject: pgsql: Do not use in-place updates for statistics import.
Date: Tue, 25 Feb 2025 01:12:26 +0000
Message-ID: <E1tmjUo-000XVD-1J@gemulon.postgresql.org> (raw)
Do not use in-place updates for statistics import.
The use of in-place updates was originally there to follow the
precedent of ANALYZE and to reduce the potential for bloat on
pg_class. Per discussion, it's not worth the risks.
