Between orm 2.1.0 and 2.1.1, a bug crept in when orm.connect is called with a postgres URL which specifies the port as part of the hostname:
Error: getaddrinfo ENOTFOUND
at errnoException (dns.js:37:11)
at Object.onanswer [as oncomplete] (dns.js:124:16)
The error seems to have been introduced in this commit: f566893
