Setting up PostGIS
PostGIS is an extension for creating spatial databases in PostgreSQL. This extension adds
support for geographic objects; it allows location queries through SQL.
This is the most popular open source extension offering many features that are rarely found
in competing spatial databases such as Oracle Locator/Spatial and SQL Server.
PostGIS is supported on Heroku Postgres in beta mode. For using this extension, you must
be using a database in the production tier and it isn't available for plans in the Hobby tier.
Besides that, it is only available in the 2.0 version with Postgres v9.2 or in the 2.1 version
with Postgres v9.3.
