ST_SubDivideExplode

It works the same as ST_SubDivide but returns new rows with geometries instead of list. A minimum of 5 vertices is required for maxVertices parameter to form a closed box.

Examples

Query:

SELECT ST_SubDivideExplode(ST_GeomFromText("LINESTRING(0 0, 85 85, 100 100, 120 120, 21 21, 10 10, 5 5)"), 5)

+-----------------------------+
|geom                         |
+-----------------------------+
|LINESTRING(0 0, 5 5)         |
|LINESTRING(5 5, 10 10)       |
|LINESTRING(10 10, 21 21)     |
|LINESTRING(21 21, 60 60)     |
