Percona Operator for PostgreSQL now allows users to expose replica nodes separately, starting from version 2.4.0. This feature enables applications to scale reads and reduce the load on primary nodes. The exposure can be changed by altering the spec.expose section in the service definition. This update aims to improve performance and reliability in PostgreSQL clusters.
