Comment (by Akash Kumar Sen):
I don't think we are regressing the `Cast()` here the query generated is
{{{
UPDATE "queries_article" SET "name" = (CASE WHEN ("queries_article"."id" =
1) THEN bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb WHEN
("queries_article"."id" = 2) THEN
bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb ELSE NULL END)::varchar
WHERE "queries_article"."id" IN (1, 2)
}}}
it is just generating the super type i.e. `varchar` instead of
`varchar(20)` in case of a `CharField`
If you can explain a little further that would be great @felixxm
