Data corruption, likely ...
I do recall that we fixed a couple of bugs recently that could result in
silly results in memory-space-needed calculations, but AFAIR they were
in maintenance commands like VACUUM FULL, and couldn't be triggered by
a plain INSERT. Still, it wouldn't hurt to try an update to 8.2.6
(or 8.2.7, fresh off the presses).
