You wouldn't have to do that. There are better ways to read system tables in the backend. See FAQ_DEV. > My first thought was to check > the existance of users against $PGDATA/pg_pwd... One question I'd have > there, is whether pg_pwd always exists (or, can be relied upon existing.)? No it doesn't and no you can't. The best way to verify a user's existence in the context of a new authentication method is to not do that at all. None of the other methods do it, the existence of a user is checked when authentication has completed and the backend starts. -- Peter Eisentraut peter_e@gmx.net http://funkturm.homeip.net/~peter
