I tried to replicate the error with a little set of data (our db
weights ~700MB) but I could not achieve it.
Now I'm checking out from the CVS server, will post a new message
today or at least tomorrow.

If I cannot reproduce the error, what is the best way to catch the
stack trace? Do I have to recompile with --enable-debug?
I read this article:
http://wiki.postgresql.org/wiki/Developer_FAQ#What_debugging_features_are_available.3F
but I never debugged postgresql with gdb. Can you give me some hint?

I am sorry for the megadelay. Thank you for supporting.
