FATAL: database <name> does not exist

Question

I am trying to create my own Spring Boot application with a POSTGRESQL database. I have started using docker to mount the database, with a docker-compose whose values ​​are as follows:

version: "3"
services:
    products-postgresql:
      image: postgres:9.6
      restart: always
      ports:
        - 5450:5432
      environment:
        POSTGRES_USER: postgres
        POSTGRES_PASSWORD: superadmin
        POSTGRES_DB: products
      volumes:
        - D:\microservicios\workspace\SpringSecurity\volumes:/var/lib/postgresql/data:rw

With the docker-compose up -d command, I managed to get it up easily,

The problem occurs to me when trying to connect with DBeaver to the database. I have configured it as a new POSTGRESQL connection, passing the connection data similar to those of docker-compose, (database = products, host = localhost, user = postgres, password = superadmin....) but it returns FATAL error: database "products" does not exist.

I've seen similar posts, like this psql: FATAL: database "" does not exist , but they don't work for me. I have verified that I don't have any other application using the same port.

Could you tell me what I may be doing wrong, or what I have left to configure? Thanks

Answer 1

Although I still don't understand why, I had to change the port of my container to 5432 (the one used by POSTGRESQL), and it finally worked for me.

version: "3"
services:
    products-postgresql:
      image: postgres:9.6
      restart: always
      ports:
        - 5432:5432
      environment:
        POSTGRES_USER: postgres
        POSTGRES_PASSWORD: superadmin
        POSTGRES_DB: products
      volumes:
        - D:\microservicios\workspace\SpringSecurity\volumes:/var/lib/postgresql/data:rw
