Wallabag container not respecting settings passed via envs

Hi,
I'm trying to setup wallabag in kubernetes, and I can't get it to use correct database. Here is my config:

```
/var/www/wallabag # printenv | grep SYM
SYMFONY__ENV__DATABASE_DRIVER=pdo_pgsql
SYMFONY__ENV__DATABASE_HOST=psql-wallabag-rw
SYMFONY__ENV__DATABASE_NAME=app
SYMFONY__ENV__DATABASE_PASSWORD=**secret**
SYMFONY__ENV__DATABASE_PORT=5432
SYMFONY__ENV__DATABASE_USER=app
SYMFONY__ENV__DOMAIN_NAME=**secret**
SYMFONY__ENV__FOSUSER_CONFIRMATION=false
SYMFONY__ENV__FOSUSER_REGISTRATION=false
SYMFONY__ENV__FOS_OAUTH_SERVER_ACCESS_TOKEN_LIFETIME=3600
SYMFONY__ENV__FOS_OAUTH_SERVER_REFRESH_TOKEN_LIFETIME=1209600
SYMFONY__ENV__FROM_EMAIL=no-reply@wallabag.org
SYMFONY__ENV__LOCALE=en
SYMFONY__ENV__REDIS_HOST=wallabag-redis
SYMFONY__ENV__REDIS_SCHEME=tcp
SYMFONY__ENV__RSS_LIMIT=50
SYMFONY__ENV__SECRET=**secret**
SYMFONY__ENV__SERVER_NAME=Your wallabag instance
```

As you can see, database engine should be postgres, but below I'm pasting the excerpt from prod.log, which suggests that it's actually for some reason trying to use sqlite.

```
