Gone is the ugly KORE_PGSQL macro that hid an overly complex state machine for the pgsql api. Gone is the pgsql array that was attached to http_requests. Gone are the callback hacks inside the pgsql api. Instead, I strongly encourage people to use the new state machine api Kore offers to properly deal with asynchronous queries. The pgsql example in examples/pgsql has been updated to reflect these changes.
