How did you create the user. Did you use the shell script or a create
user statement from inside a session in the database?

IIRC, psql (and the createuser shell script and such) treat it as if you
had double quoted its argument because of the way shells handle quotes
which would necessitate something like '"FOO"' to use a quoted uppercase
name. So, if you say psql FOO -U BAR, you're saying log into database
"FOO" as user "BAR".
