My opinion? No. I would personally not want to allow it.

I agree.

This is also good.
From my perspective, as a builder of some *very* database-centric
applications, if one has an abort contidition that proceeds to try to
establish a Savepoint as if the abort didn't exist then one needs to do some
debugging. I'm sorry I missed the original discussion on this or I would
have expressed this opinion earlier.
For that matter:
begin;savepoint; select 0/0; -- abort savepoint; -- commands will be ignored select 1; -- commands will
beignored release; -- commands will be ignoredrelease; -- abort main xact 'cause we didn't rollback
commit; -- abort message
Is the above more or less correct, Alvaro?
