Don't know abiout Oracle, but you can't disable Transact-SQL in SQL
Server 7.0 or 2000 (don't know about 2003^h5) because Enterprise Manager
and sp_help* require it.
And +1 for not installing plpgsql by default. I just had to CREATELANG
on 20-odd servers scattered across the US, and it was no big thing. Just
rolled it out with the upgrade that needed it.
