pgConsumeInput : Conn -> IO Bool

  Consume any input the server has delivered
  since the last time we ran a command that
  otherwise consumed server input.
  
  It can be useful to explicitly call upon
  `libpq` to consume input when doing something
  like listening for notifications that does
  not otherwise require making any calls to
  execute anything on the server.
  
  Returns True if successfuly and False
  otherwise.
