Feature request: Support postgres table storage options

[Anton Shutik]

There is a list of storage options (​https://www.postgresql.org/docs/current/sql-createtable.html#SQL-CREATETABLE-STORAGE-PARAMETERS) that can be applied when creating a table in postgres database. So, since django manages database schema, it would be nice to extend it to support these storage options.

It might look like:

class MyModel(models.Model):
  
    #  fields go here
  
    class Meta:
      storage_options = {
          "autovacuum_vacuum_scale_factor": 0.01,
          "autovacuum_vacuum_threshold": 1000
      }

and that would produce migration which eventually will run sql like this:

CREATE TABLE mymodel WITH (autovacuum_vacuum_scale_factor = 0.01, autovacuum_vacuum_threshold = 1000);

For now it could be done with RunSQL(sql='ALTER TABLE .... WITH (...);') migration, but it would be better to have the settings on the model class itself for better visibility and managed by django.

What do you think ?
