ST_Translate — Translates a geometry by given offsets.
요약
geometry ST_Translate(geometry g1, float deltax, float deltay);
geometry ST_Translate(geometry g1, float deltax, float deltay, float deltaz);
설명
Returns a new geometry whose coordinates are translated delta x,delta y,delta z units. Units are based on the units defined in spatial reference (SRID) for this geometry. M coordinates are preserved.

예시
Move a point 1 degree longitude
SELECT ST_Translate(ST_GeomFromText('POINT(-71.01 42.37)', 4326), 1, 0) AS wgs_transgeomtxt;
POINT(-70.01 42.37)
Move a linestring 1 degree longitude and 1/2 degree latitude
SELECT ST_Translate(ST_GeomFromText('LINESTRING(-71.01 42.37,-71.11 42.38)', 4326), 1, 0.5) AS wgs_transgeomtxt;
LINESTRING(-70.01 42.87,-70.11 42.88)
Move a 3d point
SELECT ST_Translate(CAST('POINT(0 0 0)' AS geometry), 5, 12, 3);
POINT(5 12 3)
Move points with a measure coordinate
SELECT ST_Translate('POINTM(0 0 11)', 5, 12);
POINTM(5 12 11)
SELECT ST_Translate('POINT(0 0 7 11)', 5, 12, 3);
POINT(5 12 10 11)
Move a curve and a point
SELECT ST_Translate(ST_Collect('CURVEPOLYGON(CIRCULARSTRING(4 3,3.12 0.878,1 0,-1.121 5.1213,6 7,8 9,4 3))', 'POINT(1 3)'), 1, 2);
