The argument to currval() is a quoted sequence name, so you probably
need something like this:

SELECT currval('taddress_addressid_seq');

In PostgreSQL 8.0 you can use pg_get_serial_sequence() to get the
sequence name from the table and column names:

SELECT currval(pg_get_serial_sequence('taddress', 'addressid'));
