This is indubitably a backend bug. It's still there in current sources,
too. Possibly related to an item I have on my personal TODO list:
: Why is NUMERIC not considered numeric by TypeCategory()? Why is DATE not
: considered a datetime type? Isn't this routine fundamentally broken?
: If we need a category it should be taken from a pg_type field, not
: hardwired in code...
Thomas, what say you?
