* [PATCH v50 7/8] Introduce an option to make logical replication database specific.
@ 2026-04-03 10:34 Antonin Houska <[email protected]>
0 siblings, 0 replies; 306+ messages in thread
From: Antonin Houska @ 2026-04-03 10:34 UTC (permalink / raw)
By default, the logical decoding assumes access to shared catalogs, so the
snapshot builder needs to consider cluster-wide XIDs during startup. That in
turn means that, if any transaction is already running (and has XID assigned),
the snapshot builder needs to wait for its completion, as it does not know if
that transaction performed catalog changes earlier.
Possible problem with this concept is that if REPACK (CONCURRENTLY) is running
in some database, backends running the same command in other databases get
stuck until the first one has committed. Thus only as single backend in the
cluster can run REPACK (CONCURRENTLY) at any time. Likewise, REPACK
(CONCURRENTLY) can block walsenders starting on behalf of subscriptions
throughout the cluster.
This patch introduces the possibility for a backend to declare that its output
plugin does not use shared catalogs (i.e. catalogs that can be changed by
transactions running in other databases in the cluster). In that case, no
snapshot the backend will use during the decoding needs to contain information
about transactions running in other databases. Thus the snapshot builder only
needs to wait for completion of transactions in the current database.
Currently we only use this option in the REPACK background worker. It could
possibly be used in walsender involved in logical replication too, however
that would need thorough analysis of its output plugin.
The patch bumps WAL version number, due to a new field in xl_running_xacts.
