Is it possible to have multiple names for a column?

We have a need to rename some columns, but since we can't update both
the database and the programs instantly, we'd like to temporarily
assign both names to the same column while the updates are in
progress.  Something like this would be super nifty :-)

    ALTER TABLE howdy_doody ADD NAME xyzzy TO COLUMN plugh;

I am pretty certain no such SQL command exists.  But is it possible to
do something sneaky to the internal tables so that two names point to
the same columnand everything just works?  Everything meaning updates,
inserts, etc, not further ALTER TABLE and so on.
