Replace PostgreSQL 9.1 with 9.2 in Ubuntu 12.04

Recently released PostgreSQL 9.2 comes with a heap of new features and improvements over 9.1.

These are the steps I took to remove 9.1 and install PostgreSQL 9.2 in Ubuntu 12.04.

Warning: This procedure is suitable for test and development environments only as it will wipe out all 9.1 databases


1. List currently installed postgres packages


sudo dpkg -l | grep postgres


2. Remove postgresql-9.1

*these packages were on my system

sudo apt-get --purge remove postgresql postgresql-9.1 postgresql-client-9.1 postgresql-client-common postgresql-common postgresql-doc postgresql-doc-9.1


3. Install postgresql-9.2 with official ppa


sudo add-apt-repository ppa:pitti/postgresql
sudo apt-get update
sudo apt-get install postgresql-9.2

If you cannot add the repository
sudo: add-apt-repository: command not found

Install this package

sudo apt-get install python-software-properties


4. Check postgresql is set to the default port 5432


sudo netstat -lp | grep postgresql


5. Reset to default port if necessary


sudo gedit /etc/postgresql/9.2/main/postgresql.conf

port = 5432 *change the port value in the conf file

sudo /etc/init.d/postgresql reload


6. Setup your project database / user and database.yml

  1. Thanks for posting this. It seems that the ppa:pitti/postgresql repository may not be available after 12.04 end-of-life. Meanwhile, your instructions helped me clean up a mess on a couple of upgraded 12.04.
