Cannot connect to my PostgreSQL server remotely from chainlink node terminal

Question

I have tried everyting to connect my Chainlink node up to my postgresql database with no luck. I have scoured the interwebs for answers to no avail...

Here is the error message I am receiving:

[ERROR] failed to initialize database, got error failed to connect to `host=/tmp user=root database=`: dial error (dial unix /tmp/.s.PGSQL.5432: connect: no such file or directory)

Here is my.env file:

ROOT=/chainlink
LOG_LEVEL=debug
ETH_CHAIN_ID=42
MIN_OUTGOING_CONFIRMATIONS=2
LINK_CONTRACT_ADDRESS=0xa36085F69e2889c224210F603D836748e7dC0088
CHAINLINK_TLS_PORT=0
SECURE_COOKIES=false
GAS_UPDATER_ENABLED=true
ALLOW_ORIGINS=*
ETH_URL=wss://kovan.infura.io/ws/v3/id...
DATABASE_URL=https://chainlink-db-url://postgres:Password@chainlink-kovan:5432

I have tried every configuration of the connection string. Also I am able to connect to the db via pgAdmin no problem and the dbs are publicaly accessible.

The postgresql database is on AWS.

Please change the syntax of your DATABASE_URL to:

DATABASE_URL=postgresql://"username":"password"@"public-ip-pg-server":5432/"database-name"

just change:

"username": you need to configure a new user, because the default/admin user postgres will not work for it.
"password": password of the user
"public-ip-pg-server": the public ip address of your postgresql-server
"database-name": the name of your database

PS: delete all " in your syntax (;
