AWS RDS Postgres connection failure

Question

I am getting started on AWS RDS. I am trying to create a public PostgreSQL instance (free tier) and trying to connect from my local laptop through SQL Workbench. I am following

Answer 1

You should check the following on the Amazon RDS instance:

• It is set to publicly accessible
• It is in a public subnet
• It has a security group configured to permit inbound access from your IP address on port 3306
• Your local network is not blocking the connection (try it from home, or tethered via your phone)

Answer 2

SQL Workbench was a MySQL client GUI last time I checked. So it is not surprising if it cannot connect to a database forked from PostgreSQL.

Try psql or some other PostgreSQL client software.
