[postgis-devel] collect()

[Chris Hodgson]

By flatten I suppose you mean to remove any nested collections and put 
them all in one big collection? Yes. We didn't have support for nested 
collections when "collect()" was written (that was the first thing I 
ever wrote for postgis!).

I agree, collect shouldn't flatten, but a separate function that does 
flatten would be a good idea.
