Thanks a lot for looking at this.

I tried rebasing today and found that adopting this patch to the
following recent commit to equivalence processing code would take some
time that I don't currently have.

commit 3373c7155350cf6fcd51dd090f29e1332901e329
Author: David Rowley <drowley@postgresql.org>
Date:   Sun Jul 21 17:30:58 2019 +1200

    Speed up finding EquivalenceClasses for a given set of rels

I will come back to this in a couple of weeks, along with addressing
your other comments.

Thanks,
Amit
