Construct a 2D temporal pose from a temporal geometry point and a temporal float

tpose(tgeompoint, tfloat) → tpose

The time frame of the result is the intersection of the time frames of the temporal point and the temporal float. If they do not intersect, a null value is returned

SELECT asText(tpose(tgeompoint '[POINT(1 1)@2001-01-01, POINT(2 2)@2001-01-02)',
  tfloat '[1@2001-01-01, 2@2001-01-02)'));
