[Adding Andrew Gierth]

Here is a rebased version of the patch to fix transition tables with
inheritance. Fixes a typo in an error message ("not support on
partitions" -> "... supported ..."), and changes regression test
triggers to be single-event (only one of INSERT, UPDATE or DELETE),
because a later patch will not allow multi-event triggers with TTs.

This is patch 1 of a stack of 3 patches addressing currently known
problems with transition tables.
