Обсуждение: are subtransactions not nestable?

Hello,

is it correct that a nesting of subtransactions is not possible with
postgres at the moment?
(I didn't find a TODO entry for this (even at 'exotic' features))

christof=> begin;
BEGIN
christof=> begin;
NOTICE:  BeginTransactionBlock and not in default state
BEGIN
christof=> commit;
END
christof=> commit;
NOTICE:  EndTransactionBlock and not inprogress/abort state
END

Regards  Christof

There has been some discussion of this. The fact that it is disallowed
by SQL92 is *not* the reason we don't have the feature, but it may be
responsible for it not yet being done...

We don't support it, but will add to TODO now.
