Pool settings are not passed in if a connection url is used #185
Description
I wanted to change the size of the connection pool as described here: https://github.com/brianc/node-postgres . But the connector code drops those values here: https://github.com/strongloop/loopback-connector-postgresql/blob/ce2d382a0dfecdde234eaaeb01b8c75700f38bc4/lib/postgresql.js#L78 .
It looks like an easy fix.
