We just released a new version of to-jdbc-uri, 0.4.1. A very important change in this one is that we are consolidating all our libraries into the com.carouselapps group ID, so you need to switch from including it like this:
[to-jdbc-uri "0.3.0"]
to including it like this:
[com.carouselapps/to-jdbc-uri "0.4.1"]
Aside from that, this release supports RedHat OpenShift style of URL that use the schema postgresql:// instead of postgres://. Courtesy of Pradnyesh Sawant.
