The date promotes to a timestamp at midnight; what you wrote is equivalent to Select * from sometable where DateStampColumn > '2008-03-31 00:00:00' > but when the query includes casting to date > Select * from sometable where DateStampColumn::date > '2008-03-31' > The result is correct You threw away the intraday part of the timestamp... regards, tom lane
