Yes, remove them with dpkg-maintscript-helper. This handles most of the
thinks for you.

The dbconfig stuff just needs upgrade SQL files. Look at the `sql/`
directory in `debian/`. The files are just a copy of the appropriate
files in `SQL/` (with concat when there are several of them matching the
version change). In the past, there have been some glitches because I
forgot an upgrade file (don't remember exactly) and this explains some
upgrade steps in the postinst to fix that.
