ODBC and pgpool

If a Win-32 system connects via ODBC to pgpool, does the system running pgpool
have to be permanently running or can it be rebooted without deranging open but
quiescent connections?

If it /can/ be rebooted can it also be transferred from one machine to another,
e.g. by changing the location of the IP alias?

If it /can't/ be rebooted without breaking ODBC how does one prevent this from
being a single point of failure?
