Thus, if you have a lot of client connections to the database, PgBouncer can reduce the number of PostgreSQL backends processes. Thus PgBouncer creates a pool of database connections and provides these connections to clients when the connection is required. At the same time applications do not always use connection to the database permanently, connections are often idle. PostgreSQL forks a separate process for each client connection. It reduces PostgreSQL resource consumption (memory, backends, fork). It allows PostgreSQL restart/upgrade without dropping client connections.It supports online restart/upgrade without dropping client connections. ![]() It reduces PostgreSQL resource consumption (memory, backends, fork).And below there are 3 reasons why it is be used.
