This seems to work in CVS tip. I think you're stuck in older releases
though. The syntax "foo(tablename)" is understood to mean "either a
column selection or a function call" ... but aggregates were quite
distinct from plain functions up until about a month ago, and they
weren't considered as an option at that spot in the code.
