We have followed below blog to setup Discourse to use separate postgres(AWS RDS).

Getting below error(image attached) after running ./launcher rebuild app:

Without looking too closely, I think that might mean that you created the database server, but didn’t create the discourse database? Or didn’t provide the database name in the settings?

DB setting in app.yml are as below:

env:
DISCOURSE_DB_USERNAME: discourse
DISCOURSE_DB_PASSWORD: “XXX”
DISCOURSE_DB_HOST: xxx.rds.amazonaws.com
DISCOURSE_DB_NAME: discourse

I am able to connect with this DB using pgAdmin. I have executed below commands in this DB for discourse:

CREATE USER discourse PASSWORD ‘XXX’;
CREATE DATABASE discourse OWNER discourse;

CREATE EXTENSION hstore;
CREATE EXTENSION pg_trgm;

Please help on this issue.
