Can non-superusers use PgAdminIII for non-admin tasks?

Greetings,

I have version 1.8.4 on Windows XP SP3.
My Postgresql is 8.3, installed on the same Windows box.
Everything works fine.
However, I tried logging into Pgadmin as a non-superuser, but was unable
to do so.
This non-superuser login works fine from the command line.
Correct entry is in pg_hba.conf.
Would I be correct in assuming that Pgadmin is meant for
"administration" only, not for day-to-day use by regular users?

Thanks.
