1. Does identd run on your system?
2. Is the user you pass to the connection the same as the one that actually runs the program? This is important,
becauseyou asked Postgres to check by Ident that the user who tries to connect is indeed who he says he is (hence
"sameuser").
Since you didn't show the pg_hba.conf line that pertains to localhost (127.0.0.1), I assume that it uses 'trust'.
Thiswould explain the differences in behaviour.
BTW, if you use ident, you may as well pass an empty password. It is not
checked.
