       Set terminal tab / decoration color by the server name.

       Get a random colour which matches the server name and use it for the tab colour:
       the benefit is that each server gets a distinct color which you do not need
       to configure beforehand.

Migrating from Postgres 9.0/Postgis 1.5 to Postgres 9.2/Postgis 2.0 on Heroku

This may not be relevant to many, but it's a process that I just had to go through and it was a bit tricky to figure a smooth way to make it work.

The gist of it is that you must do the following:

• Export your production database from heroku to your local machine
• Create a new, blank database with Postgres 9.2 and PostGIS 2.0
• Import your heroku database into the new local database running 9.2/2.0
• Dump the new database and upload it to S3
