In order to better support streaming queries, it would be nice if you could filter certain options down to the get-connection call (e.g., :auto-commit to invoke .setAutoCommit()).

These could either be assoc'd into the db-spec or options could be passed into all get-connection calls – the latter is probably a cleaner solution, with the usual caveat of being able to set defaults in the db-spec itself.

Suggested options to support: :auto-commit, :read-only – any others?
