I have registered the pg_sequences view patch separately in the upcoming
commit fest: https://commitfest.postgresql.org/11/865/ (The posted patch
still applies, so no new patch.)

Attached is an updated patch for the pg_sequence catalog. I haven't
received an actual technical review in the last CF, so I'll move it
forward. However, if the pg_sequences view is accepted, the catalog
patch will of course need an update. So if someone is looking here with
limited time, review the view patch first.

As before, this patch requires the "sequences and pg_upgrade" patch in
order for pg_upgrade to work.

I think together these three changes will make sequence metadata
inspection and modification easier and more robust and will facilitate
future changes in this area.
