PostgreSQL database adapter for [sharedb](https://github.com/share/sharedb). This

driver can be used both as a snapshot store and oplog.

Doesn't support queries yet.

Highly experimental.

`sharedb-postgres` wraps native [node-postgres](https://github.com/brianc/node-postgres), and it supports the same configuration options.

To instantiate a sharedb-postgres wrapper, invoke the module and pass in your

PostgreSQL configuration as an argument. For example:

var db = require('sharedb-postgres')('postgres://localhost/mydb');

var backend = require('sharedb')({db: db})

PostgreSQL errors are passed back directly.
