Check this out:
strk=# select st_isvalidreason('MULTILINESTRING((20 20, 20 20))');
st_isvalidreason
---------------------------------------------
Too few points in geometry component[20 20]
(1 row)
strk=# select st_isvalidreason('MULTILINESTRING((0 0, 10 0),(20 20, 20 20))');
st_isvalidreason
------------------
Valid Geometry
(1 row)
Interesting, isn't it ?
Martin, does JTS check for lines in a multilinestring being valid ?
