It looks to me like you must have individual rows whose COPY
representation requires more than half a gigabyte (maybe much more,
but at least that) and the system cannot allocate enough buffer space.

It could be that this is a symptom of corrupted data, if you're certain
that there shouldn't be any such rows in the table.

You really need a 64-bit PG build if you want to push
multi-hundred-megabyte field values around --- otherwise there's just
not enough headroom in the process address space.  (Something newer than
8.1.0 would be a good idea too.)
