Actually, it's a fair question considering that the 7.3 man page for
EXPLAIN says you can explain "any query". But CVS-tip documentation
says that EXPLAIN can explain
Any SELECT, INSERT, UPDATE, DELETE, EXECUTE, or DECLARE CURSOR query.
which I think is sufficient description. I'm not really eager to
enlarge the parser enough to accept EXPLAIN <any SQL command> when
it's only gonna fail anyway...
