Are the dumps of the old versions used in the buildfarm runs updated with each run? If yes, forcing a DROP EXTENSION in the problematic test modules has my favors over the dirtier tricks that would be required in AdjustUpgrade for the various database name patterns that depend on the build method. If no, well, AdjustUpgrade it is with some DROP DATABASE IF EXISTS. -- Michael
