pgpool does just that: it enables you to use the standby database as a read only while other queries are sent to the primary database only (http://www.pgpool.net/). Good product and good support (on the list°

This looks a very interesting possibility, although it is more related to automated failover than to load balancing of read only queries : http://paquier.xyz/postgresql-2/postgres-10-libpq-read-write/, depending on your client it might be supported. It is not supported - yet ? - by the node-postgres driver.

Hi,

I am also trying to split read and write queries, where reads should go to

the slave server (streaming replication) and writes to the master server.

Any tool available to perform this activity instead of two connection pool?

Actually, if you are looking for load balancing PgBouncer is better than PgPool. There is a nice article about that.

I used PgBouncer in a few of ny previous positions and found it to be very fast and efficient.
