I've created a database "bugs" and a user "bugs" (postgresql user as well as unix) and even made user "bugs" not require a password but I still get this: [root@marathon bugzilla-2.20]# psql bugs bugs psql: FATAL: Ident authentication failed for user "bugs" ... but if I [root@marathon bugzilla-2.20]# su bugs [bugs@marathon bugzilla-2.20]$ psql bugs bugs Welcome to psql 8.0.7, the PostgreSQL interactive terminal. Type: \copyright for distribution terms \h for help with SQL commands \? for help with psql commands \g or terminate with semicolon to execute query \q to quit bugs=> it works. any ideas why?
