No, really I could connect to the database that had probles! I could "COPY
table TO 'file' for *each* table of the problematic db. The problem arouse
when trying to pg_dump it or when trying to access it via libpgtcl (I use
TkSQL as you can guess from the footer ;-).
After COPYing all tables I created the file that was missing, filled with
zeros according to a mail I found of a "similar" problem. PostgreSQL
complain disappeard. As far as I can say no data seems to be lost.
I'm using PostgreSQL 7.4.2 last release of Debian Sarge.
Thanks for your time.
