Hmm... Three options:

1. Ubuntu 12.04 and 12.10 install 9.1 with this command, so we could say that laptop for Ubuntu supports any Ubuntu release >= 12.04.

2. I could go for [the PPA](https://launchpad.net/~pitti/+archive/postgresql), which has packages for non-LTS releases but will not get post-12.10 releases, meaning it's a ticking time bomb.

3. I could go for [the apt repository](https://wiki.postgresql.org/wiki/Apt), which will be there indefinitely, but only gets packages for Ubuntu LTS releases. However, these packages should work non-LTS releases. For example, quantal can use the precise package.

I'm leaning towards 3. Thoughts?
