Log Message:
-----------
Adjust grammar for plpgsql's OPEN command so that a cursor can be
OPENed on non-SELECT commands such as EXPLAIN or SHOW (anything that
returns tuples is allowed). This flexibility already existed for
bound cursors, but OPEN was artificially restricting what it would
take. Per a gripe some months back.
