Comment:

 I continued efforts to get the `Index` and `Constraint`'s `sql` methods
 return `(sql, params)` tuples but I'm having a hard time
 [https://github.com/django/django/compare/master...charettes:constraint-
 index-sql making the changes backward compatible].

 It looks like we'll have to keep playing the whac-a-mole game in 2.2 by
 extending backends schema editor's `quote_value` support for more input.
 One good side effect of these changes is that it will extend `sqlmigrate`
 coverage which also relies on appropriate output from this method.

 Here's [https://github.com/django/django/pull/11306 a PR] that performs
 the `%` escaping in `quote_value` and should address the immediate issue.

Comment:

 FWIW it's the same class of issue as #30258 which will probably better be
 fixed by making `create_sql`/`constraint_sql` methods return `(sql,
 params)` tuples. See https://code.djangoproject.com/ticket/30258#comment:3
 and [https://github.com/django/django/compare/master...charettes
 :constraint-index-sql ungoing work to make this happen].

 I'll tentatively assign to myself to try to polish the solution suggested
 above.
