How to connect Odoo with Postgresql.
Odoo running in one machine, Postgresql running in another machine.
My requirement is i have to run odoo and postgresql in two different machines.
You just need to pass "db_host=IP_of_DB_INSTANCE" & "db_port=DATABASE_PORT (by default it is 5432)"
Now, you need to change the postgres config file which will allow the IP of Odoo Instance to connect postgres.
Open: /etc/postgresql/9.5/main/pg_hba.conf and make changes in following section:
# IPv4 local connections:
host all all 127.0.0.1/32 trust
host all all IP_of_Odoo_INSTANCE/24 trust
Save the file and restart the postgres server (sudo service postgres restart)
