Can't list users from heroku psql

I have a heroku postgres add-on database with a user table. However, when I attempt to select * from user, all I get is:

  current_user  
----------------
 rtsjlhdfptlaqd
(1 row)

The table name is definitely user. There is no users table. There are definitely a bunch of users in my app, but I can’t seem to list them.

Thoughts?
