The problem is that GenericSetup does not know if your current index
is of the same type and has the same settings/properties as the index
that you specify in catalog.xml.  Apparently it is hard/impossible to
reliably compare the existing and the wanted index.  So GenericSetup
has no choice but to remove the existing index and make a new one.
