Fix inheritance count tracking in ALTER TABLE .. ADD CONSTRAINT.
Without this patch, constraints inherited by children of a parent
table which itself has multiple inheritance parents can end up with
the wrong coninhcount. After dropping the constraint, the children
end up with a leftover copy of the constraint that is not dumped
and cannot be dropped. There is a similar problem with ALTER TABLE
.. ADD COLUMN, but that looks significantly more difficult to
resolve, so I'm committing this fix separately.
Back-patch to 8.4, which is the first release that has coninhcount.
