Thanks for the hint. In the meantime we could get access to some data with
pgfsck 0.14 - great tool, great maintainer, very dedicated (Tom Lane says
pgfsck does not exist).
What I forgot to mention:
I installed lm-sensors (cvs) version and force-loaded some drivers. Then
sensors-detect gave me a segmentation fault. Do you think that could have
caused the data-corruption?
Thanks for feedback.
