In our previous posts in this series, we spoke at length about using PgBouncer and Pgpool-II, the connection pool architecture and pros and cons of leveraging one for your PostgreSQL deployment. In our final post, we will put them head-to-head in a detailed feature comparison and compare the results of PgBouncer vs. Pgpool-II performance for your PostgreSQL hosting! Let’s start by comparing PgBouncer vs. Pgpool-II features: The bottom line – Pgpool-II is a great tool if you need load-balancing and high availability.

If the objective is to limit the number of connections and reduce resource consumption, PgBouncer wins hands down. It is also perfectly fine to use both PgBouncer and Pgpool-II in a chain – you can have a PgBouncer to provide connection pooling, which talks to a Pgpool-II instance that provides high availability and load balancing.
