Subject: pgsql: Rework REPACK's documentation on clustering
Date: Thu, 10 Sep 2026 15:58:27 +0000
Message-ID: <E1x4hAQ-00000004J2u-1Ujm@gemulon.postgresql.org> (raw)
Rework REPACK's documentation on clustering
Commit ac58465e0618 moved the discussion on clustering from CLUSTER's
refpage to REPACK's, but somehow introduced a mistake regarding when
exactly can the seqscan-and-sort strategy be used with respect to btrees
(spoiler: it was 100% backwards). Fix that, but also restructure and
reword the whole subsection more fully to try and make it more coherent.
