I've stolen, borrowed and gotten inspiration from the other backends available:

Thank you all for sharing your code!

What makes this backend different is that it's for Postgresql and uses the fine datamapper Gorp. Make sure you use a somewhat new codebase of Gorp as it now defaults to text for strings when it used to default to varchar 255. Varchar 255 is unfortunately too small.
