Re: Why overlaps is not working

Thank you.

where  (a::timestamp, coalesce(b, '99991231')::timestamp) overlaps
(c::timestamp, coalesce(d, '99991231')::timestamp)

would be simplest solution.

However

select (date '20050101'::timestamp, date '20060101'::timestamp) overlaps
(date '20060101'::timestamp, date '20070101'::timestamp)

returns false

So this cannot used for date overlapping.
Which sytax to use to substract/add a minute to make this correct?
