wal_receiver_create_temp_slot

Specifies whether the WAL receiver process should create a temporary replication slot on the remote instance when no permanent replication slot to use has been configured (using primary_slot_name). The default is off. This parameter can only be set in the postgresql.conf file or on the server command line. If this parameter is changed while the WAL receiver process is running, that process is signaled to shut down and expected to restart with the new setting.

English manual coverage begins with PostgreSQL 7.4. Source history and runtime observations have their own recorded version boundaries.
