reverse proxy to postgresql with haproxy

Hey everyone, 

I am trying to configure reverse proxy to postgresql using haproxy, for this example I have the following architecture:

- node1

- node2 

- haproxysrv

Streaming replication between node1 and node2 and auto failover with repmgr.

When I issue a connection to haproxysrv to connect, I get a pg_hba.conf error telling that I haven't configured the haproxysrv to connect to the database. 

The reason that this scenario occurs is that:

HAProxy establishes 2 separate connections, 1 between the client and haproxy and one between haproxy and postgresql. the connection made haproxy haproxy and postgresql contains source ip of the haproxy itself.

HAProxy offers a "transparent" ip using proxy protocol.

According to haproxy docs and forums this feature is feasible only if the application is proxy protocol aware.

My question are:

1. is there any other solution for this issue?

2. is there anyone who knows if postgresql is proxy protocol aware?

Best regards,

Aviel B.
