Cycling redundancy check error in dump file

<font size="-1"><font face="Verdana">Hello guys, recently I made a backup of my entire database using pg_dump.<br /><br
/>The backup was OK, but for some reason when I make the copy in my storage device the back was copy wrong or something
else.<br/><br /> Whe I try to copy the file from my storage a "Cycling reduncandy check error appear", Finally I made
thecopy to my hard disk but with some damaged sectors.<br /><br /> I don't have the original database :(( only the dump
file.<br/><br /> When I try to restore, everything works fine, all tables are created, and populated, all except two
tables(big tables, in respect the others (not really big)).<br /><br /> When the pg_restore tried to copy data from the
dumpto my table "A" an "out of memory" exception occurr, (maybe is the damaged section).<br /><br /> So, I would like
to"skip" those sectors (maybe deleting damaged rows) an insert all others.<br /><br /> Please help me.. I don't found
toomuch documentation about it.<br /><br /> Thanks<br /><br /><br /> Anibal<br /><br /></font></font>
