Introduction

What is pgpool2-dbg
pgpool2-dbg is:
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.
