The problem with that is that it's pretty much guaranteed to break
pg_dump, as pg_dump always needs a lot of locks.  We could perhaps
change pg_dump to increase its limit value (assuming that that's not a
privileged operation), but the fact that a counterexample is so handy
makes me doubt that this is a better design than what we have.
