Dec/RDB (and I think Oracle as well) ignores transactions. Even
configuration commands (eg. setting date formats etc) ignore transactions.
I think the key thing here is that they view variables as part of a
programming language built on top of the database backend (like plpgsql).
As a result they separate variable management from database management.
FWIW, I would be in the '?' camp - assuming that means some kind of
session-specific setting...failing that, I'd probably start looking for an
interactive form of plpgsql, so I could get persistant variables.
