I think it's clearly *necessary* to forbid setting data_directory in postgresql.auto.conf. The file is defined to be found in the data directory, so any such setting is circular logic by definition; no good can come of not rejecting it. We already have a GUC flag bit about disallowing certain variables in the config file (though I don't remember if it's enforced or just advisory). It seems to me that we'd better invent one for disallowing in ALTER SYSTEM, as well. regards, tom lane -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
