Hackers,
While playing with code to enable subtransactions in the storage
manager, I run across this strangeness:
alvherre=# begin; begin; -- start a subtransaction
BEGIN
BEGIN
alvherre=# drop table foo; -- no such table
ERROR: no existe la tabla "foo"
alvherre=# commit;
ERROR: cannot drop active portal
alvherre=#
This happens while PortalDrop() tries to drop an active portal. In this
state, I can't do anything else short of closing the connection. But
this doesn't happen if I try to run a non-utility bogus statement
("SELECT foo"); the system then allows me to rollback the transaction.
Why is a portal kept active after a utility statement fails? I've been
reading tcop/postgres.c but I can't find what's different between
utility and non-utility.
Any clues?
