FWIW, here's the postgres entry in my /etc/passwd file
postgres:x:31:32:postgres:/var/lib/postgres:/bin/sh
The user ID of 31 indicates that he's entered as a system user.
His home directory is /var/lib/postgres
His login shell is sh, but that probably isn't important.
Umm.. did you delete the _Linux user_ postgres or just the postgres
database?

This is because you're using ident authentication for user postgres. I
don't think you can use this option with ident authentication, because
ident authentication checks to see if you're who you say you are, and as
above, it doesn't see you as being postgres, but as root. As I noted in
my previous reply, my postgres user authenticates (locally) by this
method. You will have to su to root and then su to postgres, or
directly with a command like
su -c 'su postgres'
Then, when you're done acting as postgres, you can type exit at the
command prompt and revert straight back to the user you were.
Alternatively, if all you want to do is execute one command as postgres,
you can do as I suggested in my other post.

Sure, it just takes some getting used to.
