My patch does not apply after commit 5748f3a0aa7cf78ac6979010273bd9d50869bb8e. Here is update to current master. Not null constraint is immutable too, so here is no changes in PartConstraintImpliedByRelConstraint excepts rename and comments fix.

In this patch version i also revert tests to v4 state: i use DEBUG ereport instead INFO and code path not tested. Please tell me if i must change tests some way.

regards, Sergei
