I am not sure i understand what you what.
get_updated return the installed package there is getting updated (There 
can only be on)
get_obsoleted return a installed package being replaced by a package 
with another name. There can more than one package here, do you want it 
to return pkg_id1^pkgid_id2 ?
Patryk's code should do it, _foo needs a better name :)
