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.
