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.
