I think you want to use nextval in this context. currval is used when you
have already gotten a new sequence number and want to use it in several
inserts in the same transaction.
If you make user_id a serial type, then its default value will be nextval
and you could use:
insert into users ( "user_fname", "user_lname", "user_email" ) values ('Ray', 'Hunter', 'rhunter@enterasys.com' );
to add a row.
