To put a little flesh on this:

- paperconfig/libpaper.postinst call the hook without parameters

- TeX packages' postinsts call it with option "packagename"

and the script does the following (example only for dvips)

if [ -n "$1" ]; then
  sourcedir=/usr/share/$1
else
  sourcedir=/etc/texmf/dvips
fi

papersize=`ask libpaper`

case $papersize in
  list|of|known|papers)
    :
    ;;
  *)
    error_message #debconf or stderr?
    exit 0
esac

sed -e 's/\($pattern_for_papersize\)[anysize]*/\1 $papersize/ \
  $sourcdir/config.ps > tempfile
ucf tempfile /etc/texmf/dvips/config.ps
