Thread: pgsql-server: Fix not-quite-right Assertion.

Log Message:
-----------
Fix not-quite-right Assertion.  Did not work at all in extended-query
mode (per complaint from Kris Jurka) and it was only by chance that it
didn't fail in simple-query mode.  A COMMIT or ROLLBACK has to be
executed by a portal, therefore it's wrong to suppose that there aren't
any live portals at CleanupTransaction time.
