I used to install and do:
$ sudo yum install -y postgresql94-server postgresql94
$ pg_dump -h name-of-db.us-east-1.rds.amazonaws.com -U user dbName > dump
Ok, found it.
(1) Install the repo:
$ sudo rpm -Uvh https://download.postgresql.org/pub/repos/yum/9.5/redhat/rhel-6-x86_64/pgdg-ami201503-95-9.5-3.noarch.rpm
- Update: 9.5.2-> 9.5.3 Found the repo here.
(2) Then install the package:
$ sudo yum install postgresql95
Now you can dump your RDS database to a near by ec2 instance!
