It works very well and the code, doc is clean. It's also fast ;-) Tested with 1 000 000 of lines to build a CDT ;-)

Ok thanks . I let this issue open.

@nicolas-f Do you have a test case ?

Thanks tested on PostGIS it works. This issue must be fixed on H2 side. We must check with @katzyn

PostGIS set the GEOMETRY as parent data type.

So I mean : - mixed dimension return a Geometry datatype - if srid is not equal returns an exception

Here there is a fix https://github.com/h2database/h2database/pull/3422 from @katzyn thanks to him H2GIS will be updated with the next H2 release.

@nicolas-f If you need this fix quickly we can use a compiled version of H2 from the OrbisGIS repo

@nicolas-f Ready to implement it https://postgis.net/docs/ST_Multi.html ?
