Pgpool is a connection pooling/replication server for PostgreSQL.

pgpool-II architecture

pgpool-II features

  • uses multiple DB nodes to process search queries in parallel for higher performance compared to a single PostgreSQL server
  • comes with web-based administration tool called "pgpoolAdmin" for easier operation (figure on the right)
  • up to 128 DB nodes can be attached (can be extended by recompilation)
  • can be operated using a port opened in pgpool-II for administration via network
For now, only pgpoolAdmin is released as a pgpool-II administration tool. Since C library and protocol format documentation is 

available, however, new administration tool can be created if needed.
