The postgres hba config file contains the access rules to the postgres cluster. It will be adjusted in the entry point script in future.
This allows for easier adjustments in future and for easier quoting.
Allow for more flexible configuration of the database parameters.
Always allow access via the unix domain socket and allow to configure the authentication for the access via tcp via a POSTGRES_HOST_AUTH_METHOD environment variable. By default users must be authenticated via password when using tcp and the passwords are created using the md5 authentication method.
We need to initialize the db without influence from the outside. Therefore don't allow access to the database via TCP connections for the moment.
Listen on all IP addresses of the container when starting the final db cluster. This will allow to access the database via TCP connections from the host for example when exposing the port 5432.
Avoid errors in the log when trying the create the db user twice.
For TCP access from the outside allow to set a password for the created database user.
Avoid errors when starting a container with an existing database.
Avoid errors when starting an already existing and set up database.
