Yeah, that is the SQL-standard syntax, but I think our implementation
doesn't work the way Kate would like: if "a" is an ANYELEMENT function
parameter then (I think) only IS OF ANYELEMENT would succeed. Would it
conform to the SQL spec for the test to "look through" ANYELEMENT to the
actual parameter type? Would it be reasonably implementable to do that?
