Обсуждение: pgsql: Fix overly-strict sanity check in BeginInternalSubTransaction

Log Message:
-----------
Fix overly-strict sanity check in BeginInternalSubTransaction that made it
fail when used in a deferred trigger.  Bug goes back to 8.0; no doubt the
reason it hadn't been noticed is that we've been discouraging use of
user-defined constraint triggers.  Per report from Frank van Vugt.

Since no-one seems to be testing that, should we add a regression test?
