We would rather avoid a restart if possible. Some research on the internet found a page suggesting that removal of pg_internal.init file(s) on a running system would provide the same temporary resolution as a restart??? Is this a valid temporary work around for this issue? If it is, is there a particular pg_internal.init file that needs to be removed, or just remove all pg_internal.init that can be found? Thanks, reid
