core.async interface

[donbonifacio]

Hello,

Nice work. Have you considered a core.async interface for async connections to psql?

I've thought about it briefly, and would definitely like to add core.async support. Also am pretty sure the underlying driver (pgjdbc-ng) is built on top of netty so it may be fully async, but can't say for sure.

Any ideas on how the api to use it might look?
