Invalid database name

[jawira]

Describe the issue

When using custom configuration for Postgres (database, user and password), Weblate container will stop because it will not be able to connect to database.

For example if I use the following values in ./environment, then Weblate container will never start properly:

POSTGRES_DATABASE=weblate
POSTGRES_USER=wluser
POSTGRES_PASSWORD=wlpass

The reason is that in Postgres 16 the default environment variable for declaring a database is POSTGRES_DB and not POSTGRES_DATABASE.

According to Postgres documentation:

POSTGRES_DB This optional environment variable can be used to define a different name for the default database that is created when the image is first started. If it is not specified, then the value of POSTGRES_USER will be used.

The default ./environment values will work because you are using the same value for database, username and password.

I already tried

• [X] I've read and searched the documentation.
• [X] I've searched for similar filed issues in this repository.

Steps to reproduce the behavior

1. Clone the weblate-docker repo.
2. Edit ./environment and use different values for POSTGRES_DATABASE, POSTGRES_USER and POSTGRES_PASSWORD.
3. Execute docker compose up.
4. You will see Weblate will never start because it can't establish a connection with database due to unknown database.

Expected behavior

Weblate container must start properly.

Screenshots

As you can see Postgress creates database wluser instead of weblate because POSTGRES_DB is not used.
