Hi,
This doesn't seem to make sense to me, can someone explain the rationale
behind it?
postgres=# select version();
version
---------------------------------------------------------------------------------------
PostgreSQL 8.4.4 on x86_64-unknown-linux-gnu, compiled by GCC gcc (GCC)
4.3.3, 64-bit
(1 row)
Range 1 ending on date A does not overlap with range 2 starting on date A:
postgres=# select ('2010-01-01'::date, '2010-01-05'::date) overlaps
('2010-01-05'::date, '2010-01-10'::date);
overlaps
----------
f
(1 row)
But it does when range 1 is only a single day:
postgres=# select ('2010-01-05'::date, '2010-01-05'::date) overlaps
('2010-01-05'::date, '2010-01-10'::date);
overlaps
----------
t
(1 row)
BTW, it doesn't matter whether one casts to date or timestamp

Best,
Frank.
