   1 -- Correct for the total lack of indexes in the MW 1.13 SQLite schema
   2 --
   3 -- Unique indexes need to be handled with INSERT SELECT since just running
   4 -- the CREATE INDEX statement will fail if there are duplicate values.
   5 --
   6 -- Ignore duplicates, several tables will have them (e.g. bug 16966) but in
   7 -- most cases it's harmless to discard them.
