Your probably want this instead:
insert into table_name (field_name) values (nextval('sequence_name'));
The reason why your insert fail above is that setval() should have more
parameters, but even if it had worked it does not make sense to call
setval() there. See
http://www.postgresql.org/docs/7.3/static/functions-sequence.html
Also, it's easier to use a serial column:
http://www.postgresql.org/docs/7.3/static/datatype.html#DATATYPE-SERIAL
then you can do
insert into table_name (field_name) values (DEFAULT);
