pgpool2 2.3.2.1-0ubuntu1 (powerpc binary) in ubuntu oneiric

 pgpool is a connection pool server for PostgreSQL, running between
 PostgreSQL's client and server. Any PostgreSQL client can connect to
 pgpool as if it's a real PostgreSQL server; pgpool caches the
 connection to the PostgreSQL server to reduce the overhead involved in
 establishing the connection to it. pgpool-II can also be used to
 execute queries simultaneously on several servers, that is, "parallel
 query" processing. Finally, pgpool can be used for fail over purposes.
 If the first server goes down, pgpool will automatically switch to the
 secondary server.
