I find that a bad option. A test that takes this long and has that much
setup for such a marginal amount of coverage just doesn't seem worth it.

2b) ... and create a single src/test/modules/pg_dumprestore test that
initdbs, runs installcheck, dumps, loads and compares a repated dump.

I think 2b) is by far the best choice.

By that argument we're going to add more and more isolated tests and
never merge anything.

I fail to see a single benefit of this approach.
