Re: Newbie confused about pg_hba/md5 and password field

Sorry, this seems impossible: libpq's PQsetdbLogin() doesn't allow MD5
passwords? You shouldn't have to do anything special; it should just
accept the password.PQconnectdb() has the same handling as
PQsetdbLogin().

Is it possible your libpq version is older than 7.2.1?
