Since pg.el only supports connections via tcp, a possible explanation
of psql's differing behavior could be that pg_hba.conf specifies
different authentication methods for unix domain and network sockets.
E.g., while SuSE used the "trust" method for local tcp connections,
Fedora might be using the "ident" method.
The pg_hba.conf file is documented here:
