Installation of PgBouncer: You can install PgBouncer from pgdg-common repo. It’s typically configured to hand out one of these connections to a new incoming client connection and return it back into the pool when the client disconnects.īelow are the high-level steps we will follow to set up our replication.īelow are setup details and the same will be used in this demonstration. PgBouncer maintains a pool of connections for each unique user, database pair. It can pool connections to one or more databases and serve clients over TCP and Unix domain sockets.

PgBouncer is an open-source, lightweight connection pooler for PostgreSQL.

A new Postgres client connection involves TCP setup, process creation, and backend initialization – all of which are costly in terms of time and system resources. While this design provides better stability and isolation, it does not make it particularly efficient at handling short-lived connections. For each incoming connection, the postmaster forks out a new process called as backend process to handle it. PostgreSQL has a heavyweight connection handling architecture.
