Our conclusion at the time was that cursors created inside failed
subtransactions should remain open. See the proposal and followup
discussion starting here:
http://archives.postgresql.org/pgsql-hackers/2004-07/msg00700.php
If we want to keep this behavior then we should not close all READY
cursors as per my previous patch. We should keep them open, and only
mark FAILED those cursors that are related to state reversed by the
aborting subtransaction.
I don't see any way to do this cleanly, until we have some relcache-
dependency checking on Portals (maybe anything else?). Not sure what we
can do about it right now, with 8.0.1 release tomorrow.
