AWS database connection refused

I created a postgresql instance on aws, and I made it publicly accessible. Also, I set both the inbound and outbound 0.0.0.0/0 in security group.

However, I cannot connect to this remote instance with my local computer. I also tried:

telnet <end point> 5432

It raised error:

telnet: connect to address xxx: Connection refused telnet: Unable to connect to remote host

What is the possible reason?

Update:

In the `route tables':

It is not just sufficient to select the "Publicly accessible" option and security group of RDS/DB. In addition, like any other instance it needs the ability (connected to Internet Gateway) and route to it.

The following document provides clear instructions for your DB/RDS to be accessible over the internet.
