* pgsql: Rework REPACK's documentation on clustering @ 2026-09-10 15:58 Álvaro Herrera <alvherre@kurilemu.de> 0 siblings, 0 replies; 2+ messages in thread From: Álvaro Herrera @ 2026-09-10 15:58 UTC (permalink / raw) To: pgsql-committers@lists.postgresql.org 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.
