Instruction

Well done! The functions we've shown here are used most frequently, but there are also other functions that return geometries, such as:

  • ST_Difference,
  • ST_SymDifference,
  • ST_Boundary,
  • ST_ConvexHull.

If you want to know more about these functions, we encourage you to read the official PostGIS documentation.
