How to set up PostgreSQL and connect Flask app's DB running on Heroku to the droplet?
What I got so far:
1) I went through How To Install and Use PostgreSQL on Ubuntu 14.04
2) Edit postgresql.conf to have listen_addresses = '*'
3) Edit pg_hba.conf to have host all all 0.0.0.0/0 md5
In my Flask app, which in running on Heroku, I config the DATABASE_URL to my droplet that is running the PostgreSQL 9.3: postgres://user:password@xxx.xxx.xxx.xxx:port/name
On the server, I run “netstat -plunt” to see a list of which ports are open:
tcp 0 0 127.0.0.1:5432 0.0.0.0:* LISTEN 12341/postgres
Where did I do wrong? How can I set it up so my Flask app can connect to the database?
