It seems to me that an isolation test would be a better fit here.  TAP
tests are usually a good fit for injection points if you need to do
direct node manipulations, like restarts or stops.  The whole test
posted only does SQL-ish things, and you could rely on a loopback
server as we do in the SQL tests of postgres_fdw?
