Continuing our series of PostgreSQL Data Types today we’re going to introduce the PostgreSQL ranges data type.

Range types are a unique feature of PostgreSQL, managing two dimensions of data in a single column, and allowing advanced processing. The main example is the daterange data type, which stores as a single value a lower and an upper bound of the range as a single value. This allows PostgreSQL to implement a concurrent safe check against overlapping ranges, as we’re going to see in this article.
