From 23aaa7fe401d85736ebf426626b063075a75c918 Mon Sep 17 00:00:00 2001 From: "Jonathan S. Katz" Date: Tue, 6 Jun 2023 09:51:32 -0400 Subject: [PATCH] doc: Clarify behavior of triggers/rules in a logical subscriber By default, triggers and rules do not fire on a logical replication subscriber based on the "session_replication_role" GUC being set to "replica". However, the docs in the logical replication section assumed that the reader understood how this GUC worked. This modifies the docs to be more explicit, and link back to the GUC itself. --- doc/src/sgml/logical-replication.sgml | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) diff --git a/doc/src/sgml/logical-replication.sgml b/doc/src/sgml/logical-replication.sgml index 59cf92e6a9..b18cff73ed 100644 --- a/doc/src/sgml/logical-replication.sgml +++ b/doc/src/sgml/logical-replication.sgml @@ -1654,9 +1654,13 @@ CONTEXT: processing remote data for replication origin "pg_16395" during "INSER The apply process on the subscriber database always runs with - session_replication_role set - to replica, which produces the usual effects on triggers - and constraints. + session_replication_role + set to replica.
