report whether PostgreSQL node is master or standby
Descriptionbgw_replstatus is a tiny PostgreSQL background worker to cheaply report the replication status of a node. It's intended to be polled by a load balancer such as haproxy. When installed, a background worker will be started that listens on a TCP port. A connection to this port will get a TCP response back saying either MASTER or STANDBY depending on the current state of the node.
