Apparently, you modified some objects handled by this connection.

  You *MUST* not close the connection without deciding what
  to do with the modifications -- either commit or abort them!

  Not deciding before a connection close will mean that the modifications
  linger around and are committed/aborted with the next transaction --
  i.e. in a somewhat non-deterministical way.
  This can lead to really nasty inconsistencies.

  The exception you got it *VERY* helpful!
