I need a tool that can track schema changes in a postgesql database,

BTW, I know if I use a framework with some form of model tracking
(laravel and Django), those can do it. The application I am writing does
not track model files and I really cannot compare sql schema dumps
across versions. It would be far too time-consuming.
For Python database migrations when I'm not using Django or SQLAlchemy
I've enjoyed yoyo migrations:

If you are using SQLAlchemy then I'd go with Alembic:

Btw I don't *think* this is what you're looking for, but on the Postgres
side you can also set `log_statement='ddl'` to audit the changes:

Or for something more elaborate you could use Event Triggers. The docs
have an example you could start from:
