Subject: [PATCH 2/2] Doc: configuration file handling in pg_createsubscriber

Update pg_createsubscriber.sgml to explain that recovery parameters are
written to a separate pg_createsubscriber.conf file included via
include_if_exists, and that the file is renamed to .disabled upon
completion or failure to prevent reloading on restart.
