[postgis-users] Acces to grid creation functions ?

I need to build a grid with acces to both all intersections points and
the grid geometry itself (either as multiline or multipolygon). Before
developing the function that constructs a grid I wondered how SnapToGrid
was implemented and looked at the code. It seems to me that all the
function I need already exist in the PostGIS source code (lwpoint_grid,
lwpoly_grid, ...) but unfortunately they're not exported in SQL :(

Would it be possible to export them without too much trouble?

Thanks !
