Use the standard postgres:// URL prefix for consistency

Fixes #286.

Passes make test-all.

Looks good to me! 👍

I appreciate your attention to detail in things like this. Technically the library just ignores the URL prefix, but it's good to have the standard prefix in there for clarity.

Thanks! And thanks for making it easy to contribute via the build instructions. The only rough spot was running the tests and npm installing all the missing packages as things blew up--is there a better way to do that? I'm a Postgres guy but have never really worked with node.

@deafbybeheading once you clone the repo you generally have to type npm install as it's kinda bad form to "automatically" install things when typing make test. If a single npm install didn't install everything needed to run the test...that's a bug...but I'm pretty sure it does because that's how travis runs everything & it works.

Okay, yeah, npm install is what I was missing. This is literally the first time I worked with node, so I didn't know what I was doing. Maybe add a link to node installation instructions and a note to run npm install to the contributing instructions?
