Thread: pgsql: Teach AbortOutOfAnyTransaction to clean up partially-started tra

Teach AbortOutOfAnyTransaction to clean up partially-started transactions.

AbortOutOfAnyTransaction failed to do anything if the state it saw on
entry corresponded to failing partway through StartTransaction.  I fixed
AbortCurrentTransaction to cope with that case way back in commit
60b2444cc3ba037630c9b940c3c9ef01b954b87b, but evidently overlooked that
AbortOutOfAnyTransaction should do likewise.

Back-patch to all supported branches.  It's not clear that this omission
has any more-than-cosmetic consequences, but it's also not clear that it
doesn't, so back-patching seems the least risky choice.

Branch

master
