The global setting for an instance is not affected by whether you are replicating. The replication system is supposed to set the parameter when it is applying changes, e.g., https://git.postgresql.org/gitweb/?p=postgresql.git;a=blob;f=src/backend/replication/logical/worker.c;h=eedc3a8816bc2f157e62a664bcc57b5f87530be9;hb=958fe549884928cd3bdf009993e9a05df5fd6cee#l1521 -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
