Fix typo in storage test
Update pg and pg-nest
Remove Queries.parseArray() helper method

The pg module now provides more built-in array parsing.
It seems to work for our (limited) purposes!
Enable pg.defaults.parseInt8 option
Update client pooling for latest pg

The pg module changed client pooling for versions 1.0+.
It now provides `pg.connect(url, cb(err, client, done))`.
The done method must now be called to release pooled clients.

As a result, the pg-nest module now also accepts the done method.
It now provides `new Transaction(client, [parent], done)`.
When a transaction completes, it releases the client via done().
