Name
ST_WrapX — Envolve uma geometria em torno de um valor X.
Synopsis
geometry ST_WrapX(geometry geom, float8 wrap, float8 move);
Descrição
This function splits the input geometries and then moves every resulting component falling on the right (for negative 'move') or on the left (for positive 'move') of given 'wrap' line in the direction specified by the 'move' parameter, finally re-unioning the pieces together.

This function supports 3d and will not drop the z-index.
Exemplos
-- Move all components of the given geometries whose bounding box
-- falls completely on the left of x=0 to +360
select ST_WrapX(geom, 0, 360);
-- Move all components of the given geometries whose bounding box
-- falls completely on the left of x=-30 to +360
select ST_WrapX(geom, -30, 360);
