can't connect to pg with ssl #6782

• v6.1.0
• Linux XXXX 4.1.19-boot2docker deps: update openssl to 1.0.1j #1 SMP Mon Mar 7 17:44:33 UTC 2016 x86_64 GNU/Linux (the docker official node image)
• openssl

Since upgrading to the latest node i can't connect to a postgres db using ssl.
Connection to pg on ssl on Node v 5.10.1 was working fine.

example code:
var pg = require('pg');
pg.connect(connectionString, function(err, client, done) {

where connectionString can be something like:
postgres://master:password@aws-postgres.XXX.us-west-2.rds.amazonaws.com:5432/db_demo?ssl=true

EDIT: the same happens even when omitting the ssl=true param.

I get: { error: password authentication failed for user "master"

(the password is the correct one, this error happens only on the latest node version)

is this a bug or a change that I need to handle differently?
