worked well for upgrading 9.1 to 9.3 on ubuntu server 12.04 LTS
Thanks a lot

How do I get 9.3?

Very much thanks Sir!

Thank you :)

Worked great for upgrading 9.2 -> 9.3 also

@ntucker Follow these directions to upgrade PostgreSQL 9.3 on Ubuntu http://wiki.postgresql.org/wiki/Apt

You should be looking into using pg_upgradecluster. It's much easier than this.

Worked perfect for 9.1 -> 9.3
Thanks!

👍

A bit easier way:

Add apt.postgresql.org repository by running this script: http://anonscm.debian.org/loggerhead/pkg-postgresql/postgresql-common/trunk/download/head:/apt.postgresql.org.s-20130224224205-px3qyst90b3xp8zj-1/apt.postgresql.org.sh

sudo apt-get install postgresql-9.2 postgresql-client-9.2 postgresql-contrib-9.2 postgresql-server-dev-9.2
su postgres
pg_ctlcluster 9.1 main stop
pg_ctlcluster 9.2 main stop
pg_dropcluster 9.2 main
pg_upgradecluster 9.1 main
pg_ctlcluster 9.2 main start
CTRL-D to quit su postgres
sudo apt-get remove postgresql-9.1

The gist worked fine to upgrade from 9.1 to postgresql 9.3!
Thanks a lot!

Awesome, thanks.

Thanks a lot! You saved my time!

I did it this way (for 9.3), in an automated fashion.

Thanks @ibussieres. Upgraded to 9.3.

Perfect! Works like a charm.

Thanks!

Worked great...until I got to PostGIS. Check out this post for details on dealing with the simultaneous postgres 9.1->9.3, postgis 1.5->2.x upgrade: http://sorokine.blogspot.com/2013/11/upgrading-postgresql-91postgis-15-to.html
