* [PATCH 1/5] Add REPACK command @ 2026-02-27 18:01 Antonin Houska <[email protected]> 0 siblings, 0 replies; 190+ messages in thread From: Antonin Houska @ 2026-02-27 18:01 UTC (permalink / raw) REPACK absorbs the functionality of VACUUM FULL and CLUSTER in a single command. Because this functionality is completely different from regular VACUUM, having it separate from VACUUM makes it easier for users to understand; as for CLUSTER, the term is heavily overloaded in the IT world and even in Postgres itself, so it's good that we can avoid it.
