connection pool server and replication proxy for PostgreSQL
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.
