Name

ST_PointM — Creates a Point with X, Y, M and SRID values.

+geometry +ST_PointM(+`float `+x, float y, float m, integer srid=unknown`)`;

Returns an Point with the given X, Y and M coordinate values, and optionally an SRID number.

Enhanced: 3.2.0 srid as an extra optional argument was added. Older installs require combining with ST_SetSRID to mark the srid on the geometry.

SELECT ST_PointM(-71.104, 42.315, 3.4, 4326)

SELECT ST_PointM(-71.104, 42.315, 3.4, srid => 4326)

SELECT ST_PointM(-71.104, 42.315, 3.4)
