PostgreSQL version: 9.2.4
Operating system: MacOSX
Description:
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.
