Sorry, I was a bit impatient and posted the same question in a newsgroup a few
days before. There is an answer now:
http://groups.google.de/group/comp.databases.postgresql/browse_thread/thread/36e5c65dd15b0388/1e5ff9b7e2c6863e?hl=de#1e5ff9b7e2c6863e
Of course, if anyone has an additional idea, i'd appreciate it.
Best regards,
Ralf.
