Connection failure during "PostgreSQL" DB connection from vRO

Hi All,

I am getting connection error during connecting to PostgreSQL db from my vRO "add databse" work flow (located under library\SQL).

But I can connect to that PostgreSQL db from vRA appliance through SSH connection. There I am using the database 'vcac' and the user 'postgres'.

Please see below output when connecting via SSH to that vRA apliance.

   Below is the connection parameter passing to the WF input.

below is the error log I am getting in wf console:

Is there more configuration/settings are required to connect the vRA appliance PostgreSQL DB ?  please let me know.

Thnx,
