Hi!

You live, you learn - thanks for your help :) Version is PostgreSQL 7.2.
The backend crashed when I do "select txt2txtidx(text) from article
limit 1;". This is what I get when I do "gdb psql ./core":

Core was generated by `postgres: postgres pcgames [local] SELECT
'.
Program terminated with signal 11, Segmentation fault.

The relevant cell (first row of article, column text) contains this
text: " Sie haben Spaß an PC-Spielen? Und am Schreiben? Sie

Can you make something out of this?
