I tried using pg_dump and copy, but both get errors and fail. Is there
another way that I should try to export the data? Also, I sent another
post recently trying to find out how these things happen. The drives
seem to be ok, although I still need to memcheck. This is the second
corruption in a 4 day span, but I can't find any clues to why its happening.
