Using DECLARE instead of OPEN? Yes, but that won't somehow make a cursor
involving a join updatable. See:

http://www.postgresql.org/docs/8.3/interactive/plpgsql-cursors.html

DECLARE and OPEN do not have exactly the same meaning, as explained by
the above documentation. To use a cursor defined with DECLARE you must
use OPEN - see section 38.7.2.3 ("Opening a Bound Cursor") of the
documentation.
