We need to hide the dummy FDW from pg_dump. And we need to hide it from psql's \dew, because that's used in tests and prints the owner's name, and the bootstrap superuser doesn't have a consistent name. But I didn't find a good way to hide it because it doesn't have a schema. The best I could come up with is special-casing by the name, but that seems like a pretty bad hack. For other built-in objects, psql is willing to print them out if you just specify something like "\dT pg_catalog.*", but that wouldn't work here. We could maybe do something based on the "pg_" prefix, but we'd have to retroactively restrict FDWs with that prefix, which sounds like a bad idea. Suggestions? Regards, Jeff Davis
