In 8.17.10 Constraints on Ranges of PostgreSQL 9.2.4 Documentation, a
constraint will prevent the overlapping values in an example.
But in the example, range [2010-01-01 11:30, 2010-01-01 13:00) and range
[2010-01-01 14:45, 2010-01-01 15:45) do not overlap.
No, but the second one overlaps with the range value shown in 8.17.2.
So this is correct if it's understood as a continuation of that example.
Still, it's kind of a long way from 8.17.2 to 8.17.10. It might be better
if this section were recast to use a standalone example --- Jeff, what do
you think?
