Logical Replication | Agent Skills Atlas

About this skill

PostgreSQL's logical replication — publisher-side WAL decoding + subscriber-side apply — plus everything under src/backend/replication/logical/. Loads when the user asks about logical decoding, pglogicalslotgetchanges, publications / subscriptions, output plugins (pgoutput / testdecoding), reorder buffer, historic snapshots (SnapBuild), the apply worker + parallel apply, conflict resolution (PG 18+ conflict tracking), replication origins, replication slots (physical vs logical, slot.c + slotsync.c), streaming mode for in-progress transactions, tablesync's initial COPY, or debugging apply-worker crashes / slot advancement / catalogxmin retention. Skip when the ask is about physical streaming replication (walsender/walreceiver, replication/basebackup.c, replication/walsender.c in isolation) — those are the sibling replication subsystem, mostly disjoint code paths.

Original description

PostgreSQL's logical replication — publisher-side WAL decoding + subscriber-side apply — plus everything under `src/backend/replication/logical/`. Loads when the user asks about logical decoding, `pg_logical_slot_get_changes`, publications / subscriptions, output plugins (pgoutput / test_decoding), reorder buffer, historic snapshots (SnapBuild), the apply worker + parallel apply, conflict resolution (PG 18+ conflict tracking), replication origins, replication slots (physical vs logical, `slot.c` + `slotsync.c`), streaming mode for in-progress transactions, tablesync's initial COPY, or debugging apply-worker crashes / slot advancement / catalog_xmin retention. Skip when the ask is about physical streaming replication (walsender/walreceiver, `replication/basebackup*.c`, `replication/walsender.c` in isolation) — those are the sibling `replication` subsystem, mostly disjoint code paths.
