Change security group on AWS RDS Database Instance

Question

I've created a Postgresql database instance via AWS RDS. I am now trying to connect to it from my django app, so I created a new security group and changed the imbound rules.

However how do I make this new rule active? I go onto my database instance and under "Security Groups" it only says:

default (sg-9a15a9f0)
( active )

and doesn't show the new security group I created. In the Security Group UI, I can't find a button to make the new security group active.

Any idea?

Your Amazon RDS database is currently using the "default" security group. Therefore, you have two choices:

• Modify the default security group, or
• Create a new security group (as your have done), then go to the RDS console, click on your database, then choose Instance actions -> Modify and modify the security groups that are associated with the DB instance (add the new security group, remove the default security group)

Security groups are set up within the EC2 service, so to create a new security group, go to the EC2 service, then click Security Groups on the left, under Network & Security.
