Invalid generating INDEX name of tables in migrations

[pankoffDaniel]

The problem happens when we change UNIQUE parameter in table field and launch migration.

Detail problem is below.

models.py

class Genre(Model):
    name = fields.CharField(max_length=255, unique=True)

    def __str__(self):
        return self.name

1. aerich init-db

PostgreSQL

2. Change UNIQUE parameter models.py
3. aerich migrate generates this SQL:

-- upgrade --
DROP INDEX "idx_genre_name_c78cd9";
-- downgrade --
CREATE UNIQUE INDEX "uid_genre_name_c78cd9" ON "genre" ("name");

4. aerich upgrade raises an error:

tortoise.exceptions.OperationalError: index "idx_genre_name_c78cd9" does not exist
