This we know, and therefore we do
purge_ucf_file () {
local conffile="$1"
purge_file $conffile
if [ -x /usr/bin/ucf ]; then
ucf --purge "${conffile}"
fi
}
purge)
# purge texmf_parts
for file in $UCF_FILES; do
purge_ucf_file /etc/texmf/$file
done

Indeed I don't completely understand it, or your interpretation of it.
Here's the relevant part:

I would say from this that files left in /var/lib/ucf/cache aren't our
fault, but simply ucf's. The error message comes before our postinst is
called with "purge". The ls-R file is our responsibility, of course.
