Here's a patch that fixes everything I was sure was an actual bug. The
rest of the warnings seem to be caused by the tool not knowing that
elog(ERROR) throws a longjmp and things like "we never unref this
object, so it can't disappear mid-execution".
Attached are patches for HEAD and for 9.1.x (since splitting plpython.c
in 9.2 was kind of my idea I felt bad about you having to back-patch
this so I tried to do the necessary legwork myself; I hope the attached
is what you need).
BTW, that tool is quite handy, I'll have to try running it over psycopg2.
Cheers,
