That was my initial approach, but it was getting a bit messy.

FDWs don't have a schema, so we can't put it in pg_catalog, and names
beginning with "pg_" aren't restricted now. Should I retroactively
restrict FDW names that begin with "pg_"? Or just use special cases in
pg_dump and elsewhere? Also I didn't see a great place to document it.

Admittedly, I didn't complete the dummy-FDW approach, so perhaps it
works out better overall. I can give it a try.
