Comment:

 So here's a documentation question: I created 8 different version of
 ST_MapAlgebraFct, with different permutations of arguments. They can be
 grouped into 4 variants with and 4 variants without the last argument
 (text[]). Does it therefore make sense to have 4 variants documented, with
 the last argument (text[]) marked as optional?

 In addition, should the simplest variant be documented first, then the
 more explicit variants later?
