Can there be a way of installing the MB postgres unaccent extension without overwriting the postgres unnacent.so lib that comes with postgresql90-contrib package?

The fact that apparently this is required in order to properly run the MusicBrainz server hurts us in the context of deploying RPM packages because this implies a package that overwrites a file from another package.

Can a solution similar to the postgresql-musicbrainz-collate extenstion be implemented ?
