error during pg_dump

I got this error while doing a pg_dump on one of my tables -- any ideas?

pg_dump: ERROR: invalid memory alloc request size 18446744073709551613
pg_dump: SQL command to dump the contents of table "users" failed:
PQendcopy() failed.
pg_dump: Error message from server: ERROR: invalid memory alloc

Did you really transcribe that accurately? The number's an order of
magnitude too large to fit in even an int64, and it's quite hard to see
how a value wider than int32 could arrive at palloc anyway.

In any case, I suppose this is a corrupted-data issue; you need to find
and delete the corrupted row (or rows). There are past discussions in
the archives that might help.
