SQLAlchemy or PL/pgSQL?

Question

Python

Hello dear. I have a question and in order to find the correct answer I need your opinions.
I am learning Flask and for further work I needed to install MySQL. But due to a stupid habit of choosing the best, I googled and chose PostgreSQL. I dug a little more and then came to SQLAlchemy, which makes it possible to write code without thinking about SQL dialects. And the code becomes independent of any database. That's all I could find out about SQLAlchemy. What do you choose and why?
It is desirable that there be good functionality, ease of learning and a bright future :D

Answer 1

For learning - use orm - alchemy or jang
For production - use orm
When you become a specialist in IB, sql and python - write raw queries

Answer 2

Postgres + postgres driver + SQL ALchymy = something like that.
