We've received a client's database which was giving errors and refusing to be
backed up; at this point we do not know what's happened to the database to
corrupt it (likely a hardware or power failure, etc.)
The error that is being given when trying to do selects on the affected table
or doing a pg_dump is:
ERROR: invalid attribute number 32533 for largedata
We've tried to see if we can resolve this error, but
- there's no error number associated with it, so it's difficult to reference
- there doesn't seem to be any information on it (searches for 'invalid
attribute number' only return past troubles for which this error was only a
symptom, no the main issue).
As I mentioned, we've tried doing a pg_dump, vacuuming the affected table, and
trying to select anything from it, all resulting with the error above. At this
point, we're left wondering:
- what does this error mean exactly (is it a problem with the data? with the
schema?)
- how should we go about dealing with it (what else should we try?)
Of note: we ARE able to pg_dump the database if we exclude the affected table;
right now our plan (short of any successful solutions) is to recover the
table's data from a known good backup to recover the table data.
Any suggestions/info appreciated.
Seb
