I'm extremely sorry about the post in this thread ! Had a brain cramp, my
appologies. Should have been Re: [SQL] SQL function parse error.
Terribly sorry again !

To everyone interested, check out Tom Lane's and Bruce's comments on
pgsql-hackers:

There seems to be some consensus towards removing $ from the list of allowed
operator characters.

Well, I think I've thunk something up.  Of course I'm happy to submit
my modification for distribution or ridicule, as the case may be.
Where should I submit this?

I made a function noupcols() which takes one or more column names as
arguments.  The function then creates a new tuple by getting the old
values for those columns, and then doing an SPI_modifytuple on the new
tuple using the old values for those columns.

I'm kind of flying by the seat of my pants here, so if anyone would
care to critically review my code, by all means...
