I don't think anything. I could be wrong, but my understanding is that
if the primary goes down, you have to restart pgpool after primary comes
back up. It doesn't toggle back and forth from primary <-> secondary
when necessary, it only goes primary->secondary. I played with pgpool
for a while and came up with effectively the same confused question.
