   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.
