Clojurians Log v2

If anyone is interested I've published a very basic PostgreSQL driver (based on the leveldb driver) for konserve that seems to be usable with datahike - although it does require patching the datahike.api file. I plan to use it as a persistence layer for some prototypes / small apps and this should allow deploying to Heroku. https://github.com/retro/konserve-pg

I'm also interested in feedback - how to make it better and more usable
