Are you doing anything multi-threaded in those scripts? libpq is not
thread-aware --- it's up to you to ensure that only one thread touches
a given PG connection (only one at a time anyway).
That might have nothing to do with your problem, but no other theories
come to mind with the limited info you've provided...
