I've pushed and backpatched the fix. Attached are similar fixes for the
existing pg_upgrade checks for pg_catalog.line and pg_catalog.unknown
types, which have the same issues with composite types and domains.

There are some additional details & examples in the commit messages.

I've kept this in two patches primarily because of backpatching - the
line fix should go back up to 9.4, the unknown is for 10.
