Constructing A Range Of Dates

PostgreSQL offers a number of range types including the daterange type. This can be constructed using the daterange() function with two strings representing the lower and upper bounds of the date range respectively.

> select daterange('2015-1-1','2015-1-5');
        daterange
-------------------------
 [2015-01-01,2015-01-05)

The lower bound is inclusive -- indicated by the [ character -- and the upper bound is exclusive -- indicated by the ) character.
