Postgres(10.3) permission issue

I have a PosgresQL(10.3) database(django). The database is created by user_owner, an has a complete structure but without rows data.

I want to access the database remotely. With the user_owner I can access remotely the database with almost no issues.

But, I created a secondary user, user_remote. I want to use this user,instead of the user_owner because I will give him temporary remote access, and the user_owner is used for backend code.

For this user I give the privileges:

 GRANT ALL PRIVILEGES ON DATABASE name_db TO remote_user;
 GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO remote_user;

When I try to connect with user_remote, remote , I can connect to the database, but If I try to do something else, like SELECT, I get an error:

[42501] ERROR: permission denied for relation table_name

If I connect in the database and give a table privileges, with:

GRANT ALL ON table_name TO user_remote;

works.

But, I have many tables, and what I want to achieve:

1. give access to user_remote access to all tables in one/few steps, not table by table
2. I don’t want user_remote to have all privileges, but just to do row operations(drop,update,insert)
