Note: RENAME appears to be broken as of PostgreSQL 7.3. Fixing this
is of low priority, since ALIAS covers most of the practical uses of
RENAME.
Seems to work though. Could somebody please confirm/reject that this
has been fixed?
It "works" only for very small values of "works". See the links in
the TODO item for it.

Tom, the TODO item says:
Server-Side Languages
- PL/pgSQL
- Fix RENAME to work on variables other than OLD/NEW
but it seems to already work. I have tested it on 8.2 and have not noticed any problems.
