I was just about to say the same. Another thought is that you might as
well declare the input type as "any" --- using "anyelement" just causes
the parser to waste a few cycles checking for argument/result type
conflicts that can't exist here.

I don't like gettype() as the function name: it's not particularly
readable and it seems to infringe on application namespace. It should
be pg_something ... maybe pg_typeof() ?

Oh, another thing: it shouldn't be STRICT. Nulls have perfectly good
types.
