Subject: pgsql: doc: Adjust documentation for vacuumdb --missing-stats-only.
Date: Wed, 30 Jul 2025 18:05:36 +0000
Message-ID: <E1uhBBH-001WyV-2N@gemulon.postgresql.org> (raw)

doc: Adjust documentation for vacuumdb --missing-stats-only.

The sentence in question gave readers the impression that vacuumdb
removes statistics for a period of time while analyzing, but it's
actually meant to convey that --analyze-in-stages temporarily
replaces existing statistics with ones generated with lower
statistics targets.
