Re: python patch

Not a problem.  I would rather them be correct.

Worth noting that the first patch is what attempts to fix the long ->
int overflow issue.  The second patch attempts to resolve "attisdropped"
column use issues with the python scripts.  The third patch addresses
issues generated by the implicate to explicate use of "cascade".

I assume your reservations are only with the second patch and not the
first and third patches?
