What version of python are you using? I just ran "make installcheck"
using python 2.1 and the tests passed. I know python 2.2 and later will
fail because the rexec module used to create the restricted execution
environment has been deprecated, and any attempt to use it results in
RuntimeErrors being thrown.

The new-style classes introduced in python 2.2 allow you to trivially
breakout of the restricted environment. There are also known bugs in
the rexec bugs in python 2.1. It's probably wise to not install
plpython as a trusted language, at least until the restricted
environment can be restored.
