+-- Add extra option fields to the ipblocks table, add some extra indexes, 
+-- convert infinity values in ipb_expiry to something that sorts better, 
+-- extend ipb_address and range fields, add a unique index for block conflict 
+-- detection.
+
+-- Conflicts in the new unique index can be handled by creating a new 
+-- table and inserting into it instead of doing an ALTER TABLE.
