Another +1 on the per-table setting. Or a config file setting to disable
this for the instance.
We have a 200GB DB that is mostly large text (>1MB) that is not searched
with substr. If we see a blowout in size of even 3x, we will not be able
to upgrade due to disk space limitations (at least without paying for a
lot of disks on mirror servers and hot-standy servers).
