A continuación se dan ejemplos de uso de tipos alfanuméricos temporales.

-- Agregación temporal

A continuación se dan ejemplos de uso de tipos de puntos temporales.

-- Valor en una marca de tiempo
SELECT CarId, ST_AsText(valueAtTimestamp(Trip, timestamptz '2001-01-01 08:10:00'))

-- Distancia temporal
SELECT T1.CarId, T2.CarId, T1.Trip <-> T2.Trip
