Обсуждение: invalid memory alloc request

An insert query had been running fine until lately with the following memory error:

Can't execute statement: ERROR:
invalid memory alloc request size 18446744072762367400

It is running on Postgres 8.2.4, and the database size is less than 2G.

T he requested memory size is ridiculous high, does any one know what is causing this?

Thanks,
Jessica

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).
