That's just bizarre. The only thought that comes to mind is that the
error is in a trigger or rule attached to old_log, but you aren't
showing any such thing in your psql \d output.
If you pg_dump the tables and restore into another database, can you
still replicate the misbehavior? In any case it might be helpful to
look at "pg_dump -s -t table" output for these two tables.
Another thing that might be relevant is whether you've ever dropped
any columns in either table?
