ValidateTopologyPrecision — Returns non-precise vertices in the topology.
geometry ValidateTopologyPrecision(
name toponame, geometry bbox, float8 gridSize)
;
Returns all vertices that are not rounded to the topology or given
gridSize
as a puntal geometry, optionally limiting
the check to the area specified by the bbox
parameter.
