Thanks. As far as I can see this fixes the bugs that were reported.
I've been giving the patches a look and it caused me to notice two
additional bugs in the same area:
- FKs in partitions are sometimes marked NOT VALID. This is because of
missing initialization when faking up a Constraint node in
CloneFkReferencing. Easy to fix, have patch, running tests now.
- The feature added by d6f96ed94e73 (ON DELETE SET NULL (...)) is not
correctly propagated. This should be an easy fix also, haven't tried,
need to add a test case.
