Feature: Add postgresql

[yaronsumel]

I got requests to add postgresql as optional storage handler.. any other interest in that ?

[sebastianmacias]

Definitely! digota looks very interesting and I will be soon evaluating it for a project, however postgresql support is a must in my case.

K! one of the key points here is to be flexible as possible.. so it is going to happen soon with other storage handlers as well.

I'd also like postgres support. Would be useful because it could then run on google's GKE and cloud-sql

The postgresql is my first selection
