Tom, since you check pg_statsistic in the optimizer for the most common
value, should we downgrade the pg_attribute.attdisbursion value when we
know the value is not the most common value?  Are you doing that
already?

Yeah, we already do.  In fact the last tweak in that area was to reduce
the ratio we multiply by in just that situation.  It's a poor substitute
for actually having better stats of course...
