Seems like we could certainly stick these into a contrib directory.
I'd be a little hesitant to cram so many names into the default
installation, for fear of conflicting with existing user setups ---
but a contrib distribution has no such constraint. (Also, aren't
some of these the same as ODBC-standard functions? I believe Thomas
has been working on including all the ODBC functions into the backend,
so you could save him some work there.)

What I have done so far cleans up NULL handling, but I have not tried to
do anything about functions accepting or returning sets. I think the
plan is to see if we can support set functions better as part of the
querytree redesign scheduled for 7.2.
