I have a backup done with "pg_dump" utility.
For some reason the backup file has 8 phisical bad sectors (17 KB of data)
Now when I try to restore the backup all tables are created successfully
and data of almost all tables restores successfully too, but one table
(the most important) appear empty.
When I do a pg_restore <backup_file> its show all sql instructions and
data until arrive to the "damaged sector" and throws a "out of memory"
exception.
I want to know if is possible to fix the backup file removing the blocks
in the "bad sectors" in order to restore all other information.
something like file dump surgery :)
Thanks!
