Pgpool and pgpool-II precisions

Hi,

I have a few questions regarding pgpool and pgpool-II.

I've read this presentation, but I'm afraid it is too old now to be
relevant enough.

http://www.sraoss.co.jp/event_seminar/2006/pgpool_feat_and_devel.pdf

Here are my questions :

Is there a tool that helps managing pgpool (and Slony, eventually). The
customer I work for uses Patrol to manage its IT. Is there a way to plug
pgp and Slony on it ?

How many nodes may I work with when using pgpool-II ?

Are there different politics to reuse connexions
(request/transaction/session) ?

Does pgpool interfere on encodings (both sides)? I wonder which encoding
is taken if a client on an fr_FR.UTF-8 server connects to a Latin1 PG
server through pgpool on a host which environment may be in en_US.UTF-8,
for instance. (Sometimes people don't care about the environment when
installing servers, and when calling for help, it's sometimes too late...)

Thanks in advance,

Best regards,
