[postgis-devel] force_collection()

[Paul Ramsey]

The semantics of force_collection are almost, but not quite, the same 
between 0.9 and 1.0. The difference is causing mapserver breakage in 
very rare cases (like the demo I am doing for MUM).

I think you will find that

asbinary(force_collection(collect(the_geom))) where the_geom is a 
multilinestring returns a different result between 1.0 and 0.9

I do not know if we care enough to change it, but it is a backwards 
compatibility thing for mapserver in rare cases.
