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
After RDS upgrade to 9.5.2 I get this:
pg_dump: server version: 9.5.2; pg_dump version: 9.4.5
pg_dump: aborting because of server version mismatch
I can't find a proper package for Amazon Linux
This didn't help me: http://tecadmin.net/install-postgresql-9-5-on-centos/
Can you?
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!
You can actually install a newer version of Postgres with the Amazon Extras Library: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/amazon-linux-ami-basics.html#extras-library
I needed Postgres 10, so for me the command was:
sudo amazon-linux-extras install postgresql10
You can view a list of extras Amazon Linux provides by using this command:
amazon-linux-extras list
