Pgpool-ii is a middleware that works between postgresql servers and a postgresql database client. it provides the following features:

* connection pooling
* replication
* load balance
* limiting exceeding connections
* parallel query
pgpool-ii talks postgresql's backend and frontend protocol, and relays a connection between them. therefore, a database application (frontend) thinks that pgpool-ii is the actual postgresql server, and the server (backend) sees pgpool-ii as one of its clients. because pgpool-ii is transparent to both the server and the client, an existing database application can be used with pgpool-ii almost without a change to its sources.

this package contains the debugging symbols for pgpool-ii.
