Unfortunately, pg_dump didn't go through. I already did some REINDEXing
and VACUUMing. Vacuum fixed something (sorry, don't I recall the
message), but SELECTing from the table still fails, as some fields of
course reference now deleted toast data:
ERROR: missing chunk number 0 for toast value 479667
Is there any way to find this toast value 479667? Something like the
following query:
SELECT id FROM my_corrupt_table
WHERE pg_is_toasted('column')
AND pg_toasted_value('column') == 479667;
Again, I'm fine loosing the data in the toasted fields in question. But
I'd rather like to save the remaining data. I've already tried UPDATing
a field I've found manually (by trial and error). That helped and I can
now select that row again (having lost only the field's content).
Is there some sort of error recovery tool? Or should VACUUM fix such
things on special request?
Regards
Markus
