Oh, that's interesting. Looking more closely, the test in
PageRepairFragmentation()
if (itemidptr->itemoff < (int) pd_upper ||
itemidptr->itemoff >= (int) pd_special)
ereport(ERROR,
(errcode(ERRCODE_DATA_CORRUPTED),
errmsg("corrupted item pointer: %u",
itemidptr->itemoff)));
is slightly tighter than what pg_filedump does:
// Make sure the item can physically fit on this block before
// formatting
if ((itemOffset + itemSize > blockSize) ||
(itemOffset + itemSize > bytesToFormat))
printf (" Error: Item contents extend beyond block.\n"
" BlockSize<%d> Bytes Read<%d> Item Start<%d>.\n",
blockSize, bytesToFormat, itemOffset + itemSize);
I'm guessing that the lack of a check for itemOffset < pd_upper is why
pg_filedump is failing to notice anything wrong. Do you want to add one
and try again?
