I am using PostgreSQL as my database and using django tenant schemas. But when I run the following command python manage.py migrate_schemas --shared I get the error saying

I've been working on a project for CS50-Web for a while now and I was changing some of my models trying to add a unique attribute to some things. Long story short it wasn't working how I wanted so I went back to how I had it previously and now something is wrong and I can get it to migrate the changes to the model. I don't understand what to do because it was working fine before. Please can someone help I so frustrated and annoyed that I've broken it after so many hours of work. Sorry I know this error code is long but I don't know which part is important.

Just try these 3 commands for migrations:
python manage.py makemigrations appname
python manage.py sqlmigrate appname 0001 #This value will generate afte makemigrations. it can be either 0001, 0002 or more.
python manage.py migrate
And see if it solves this error

django.db.utils.ProgrammingError: relation "app_bugs" already exists
How to fix it?
..................................................................
In database, the relation has already been created. You might have two references for bugs relation in your django app models.py file. If you find multiple reference please rename it differently.
If it's isn't the case you can resolve the error in 2 days:
Delete database entirely. If you're using sqlite3 db then just delete db.sqlite3 file present in your project directory.
Delete all migrations file entirely and recreate and apply it.
everyone. I newbie in this field. So, After I finished makemigrations. then I migrate this error code occurs. I try to solve it but still stuck. please guide, I attach my error code as below.

django.db.utils.OperationalError: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
Can you please give me advice - which postgres settings i should change in order to solve this issue?
I try set statement_timeout = 0, idle_in_transaction_session_timeout = 0 with no result.
Migration:

I am trying to follow the getting started tutorial for django oauth toolkit from:
https://django-oauth-toolkit.readthedocs.io/en/latest/rest-framework/getting_started.html
When I run migrate, I get this error:
File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/django/db/backends/base/schema.py", line 1003, in _constraint_names
if type_ is not None and infodict['type'] != type_:
KeyError: 'type'
Any help would be appreciated.

It seems this error was caused by oauth2_provider migration. You should be able to fix it by going into {your venv}/Lib/site-packages/oauth2_provider/migrations and delete all your migrations files (except init.py) and then run again migrate. Hope this will be helpful
