[postgis-devel] ST_GeometrySplit

[strk]

Brain picking you guys about a ST_GeometrySplit.

The cases of interest seem to be:
 - Split polygon by line
 - Split line by line
 - Split line by point

Initial questions:
 - Should we allow multi-segment "blade" lines ?
   (where a single polygon or line might be cut in multiple pieces)
 - Should we allow multi-component inputs ?
   (where the "blade" might cut a single component)

Both questions are related to the kind of returned output,
that is: should output be always composed by 2 parts or
possibly multiple parts ?

Comments welcome.
