I'm trying to remove all the unused indexes from my db and figured that
there are some primary key indexes created by Django. Following is an
example for a model that I need to remove those indexes from.
{{{
class TeamName(models.Model):
team_name = models.CharField(max_length=64, primary_key=True)
}}}
I tried adding db_index=False to above team_name field expecting it to
avoid creating the index for the primary key. But it does not create a
migration for this change. Thus it does not remove the corresponding index
with name ending "_like". All of my models having CharField as primary key
behaves the same.
