So what are doing all not removed keys from this xml files ?
Example from my /etc/gconf/gconf.xml.defaults/%%gconf-tree-af.xml:

		install 	upgrade 	uninstall 

%pre 		$1 == 1		$1 == 2		-- 
%post 		$1 == 1		$1 == 2		-- 
%preun 		--		$1 == 1 	$1 == 0 
%postun 	--		$1 == 1		$1 == 0 

If you want replace register/unregister subset schemas by reinstall all
files you need hook only in %post and %postun .. *unconditionaly*. No
matter is it first install, upgrade or uninstall.

BTW. I have small modification %post/%postun script template:

if [ -x %{_bindir}/gconftool-2 ]; then
        export GCONF_CONFIG_SOURCE=`%{_bindir}/gconftool-2 --get-default-source`
        rm -f $GCONF_CONFIG_SOURCE/*
        %{_bindir}/gconftool-2 --makefile-install-rule /etc/gconf/schemas/*.schemas >& /dev/null
fi

It will allow remove all "Requires(post,postun): GConf", "Prereq: GConf"
or Requires(post,postun): /usr/bin/gconftool-2 rules.
