Automatic reconnection

Right now, if the connection to the server is lost (i.e. restart PostgreSQL server), the application needs to be restarted to get reconnected. I think this would be a nice feature to have :)

Here's the exception I get when I stop and then start the PostgreSQL server:

root[ERROR] java.lang.Exception: Fatal: EOF before 5 bytes could be read.Bytes

The reported failure points to BitVectorSocket.scala:72 while PostgreSQL is stopped and restarted. Begin by tracing that read failure and the connection lifecycle; done means the application reconnects after the server returns without an application restart, with behavior verified around this scenario.
