That says that you have a value too wide to fit in an index entry. If
it was from data that fit before, then I think this must indicate that
data on-disk has gotten corrupted, causing some datum to appear longer
than it was --- and then when vacuum tries to rebuild the index entry
for that row, you get a failure.
In any case I'd say this is a consequence of your kernel-level problem.
It cannot be the cause.
