By default PgBouncer using Port 6432 you can confirm using OS command netstat. Once installation is done start and enables PgBouncer service using below commands. ![]() 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.
