I'm not opposed to adding a new test case at this point in the cycle,
but as written this one seems more or less guaranteed to fail under
load. You can't just sleep for worker_spi.naptime and expect that
the worker will certainly have run.
Perhaps you could use a plpgsql DO block with a loop to wait up
to X seconds until the expected state appears, for X around 120
to 180 seconds (compare poll_query_until in the TAP tests).
