It is that easy, and that is a good way to do it.
Alternatively, if you need to support older PostgreSQL version for
example, you could use a "SELECT currval('sequence')" query after the
INSERT.
Much of the of discussion you saw were probably about implementing the
JDBC getGeneratedKeys() function that some applications need for
portability reasons, or because of middleware that doesn't know how to
do INSERT RETURNING. PostgreSQL driver doesn't support that at the
moment, but as long as you don't need it, you'll be fine.
