[postgis-devel] ST_CollectionExtract with empy collection

[Andrea Peri]

Hi,

I notice this
query
SELECT ST_AsText(ST_CollectionExtract(ST_GeomFromText('GEOMETRYCOLLECTION
EMPTY'),2));

return
GEOMETRYCOLLECTION EMPTY

I don't know if it is a bug or a wanted feature

But I see this like a problem because I have to populate a table of
MultiLinestring , and use
ST_CollectionExtract to retrieve the multilinestrings.
