Adding this dependency adds a ton of DEBUG logging

[devonzuegel]

I believe this library is setting some sort of global logging variable, because as soon as I added it, I got an overwhelming number of DEBUG logs. They're mostly from Jetty but also from a few other things, which is what makes me think it's global.

This might be a hint — when I run lein deps :tree | less, I see that clj-postgresql pulls in a library called logback, which might be the culprit:

...
 [clj-postgresql "0.7.0"]
   [clj-time "0.9.0"]
     [joda-time "2.6"]
   [com.jolbox/bonecp "0.8.0.RELEASE"]
   [net.postgis/postgis-jdbc "2.1.7.2" :exclusions [[postgresql]]]
     [ch.qos.logback/logback-classic "1.1.3"]
     [ch.qos.logback/logback-core "1.1.3"]
...

P.S. Thanks for making this library! It's really useful.
