Lost data after fixing the error with entering the role?

Question

PostgreSQL

During the time when I did not use the user in the docker-compose file, I got an error, but I could manage the database, and manipulate data from the PostgreSQL database tables on the AWS server.
Mistake:

database |      Connection matched pg_hba.conf line 94: "host all all 0.0.0.0/0 md5"
database | 2020-09-16 00:40:28.127 UTC [55303] FATAL:  password authentication failed for user "postgres"
database | 2020-09-16 00:40:28.127 UTC [55303] DETAIL:  Password does not match for user "postgres".

But then I fixed it by defining the user and password through docker-compose.yml, and from that moment on, the tables in my database were updated, and the data in the tables turned out to be empty! So, after all this, I had 2 new databases in pgAdmin4 (template0 and template1) and I could not connect to one of them! But then they disappeared altogether!
