Subject: pgsql: Add functions pg_set_attribute_stats() and pg_clear_attribute_st
Date: Tue, 22 Oct 2024 22:24:42 +0000
Message-ID: <E1t3NIx-001xv3-6p@gemulon.postgresql.org> (raw)

Add functions pg_set_attribute_stats() and pg_clear_attribute_stats().

Enable manipulation of attribute statistics. Only superficial
validation is performed, so it's possible to add nonsense, and it's up
to the planner (or other users of statistics) to behave reasonably in
that case.

Bump catalog version.
