CONCURRENTLY` exists since PostgreSQL 14, cannot run inside a transaction block, and works in two transactions; if the session is interrupted between them the partition is left in a 'detach pending' state, visible in `\\d+`, and must be completed with `ALTER TABLE ... DETACH PARTITION ... FINALIZE` before anything else can be done with it. On 13 and earlier the plain `DETACH` takes an `ACCESS EXCLUSIVE` lock on the parent for its duration, which briefly blocks inserts into the newest partition. The tool the article names for creating partitions, pg_partman, also runs the retention side (its `retention` and `retention_keep_table` settings), so one job can cover both ends.","created_at":"2026-09-15T19:47:27.184014+00:00","kind":"observation"}],"next_cursor":null}
