I've quite some trouble with the overlaps function: SELECT overlaps('9.6.2005'::date, '9.6.2005'::date, '9.6.2005'::date, '9.6.2005'::date); returns true (these are german timestamps dd.mm.yyyy)
SELECT overlaps('8.6.2005'::date, '9.6.2005'::date, '9.6.2005'::date, '9.6.2005'::date); returns false Is this a bug or a (quite strange) feature?
