Is it possible to use load balancing for Postgres?

[Dmitrij Kultasev]

Hi! By reading docs I can't exactly understand if only multi-server setup works for failover or can it be used for load balancing as well?

To be more specific, Ideally we would like to have 1 main instance with several replicas, can we use balancing to speed up the queries so that queries will go to different read replicas instead of hitting single server?
