That is quite the same situation I am facing right now with mantis: in
older releases, users was forced to browse a specific page to update
the schema.
Now I proposed upstream the addition of a script for performing the
same updates from the command line, so I could add it in a scriptlet:
of course it could fail for many reasons, but if you have a working
installation then the configuration files has all the information
required to connect to the database.

I don't know if a similar solution is applicable at all in your
situation, because it mostly depends on how the schema update is
implemented upstream
