That happens at startup when pg_control is read, before streaming starts. Remember that you need to start with a base backup. We also check that the system_identifier in the standby matches that in the primary, when the connection is established. That protects you from starting streaming from wrong base backup. -- Heikki Linnakangas EnterpriseDB http://www.enterprisedb.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
