bug: postgres args described in the doc are not implemented invludferf

[Goopil]

Describe the bug

in the Readme and une the default values file.
There is a mention on the params args to configure the postgres connection string

But when looking at _helpers.tpl. Only the postgres.args seems handled

visible here

https://github.com/search?q=repo%3Alangfuse/langfuse-k8s%20args&type=code

To reproduce

configure a postgres args in the auth options (like a different schema with search_path=my-custom-schema)

Chart version and values.yaml configuration

Hi @Goopil! I'm Dosu and I’m helping the langfuse-k8s team.

You're right—while the docs and values.yaml mention postgres.args for passing custom Postgres connection arguments (like search_path), the Helm chart only sets this as the DATABASE_ARGS environment variable if provided. There’s no further processing or integration in the deployment templates, so whether this works depends entirely on the Langfuse app reading and using DATABASE_ARGS as expected. If you need to ensure custom args like search_path are respected, you may need to enhance the Helm templates or confirm the app’s support for these env vars. The current implementation is limited to this environment variable assignment and doesn’t guarantee full support for advanced connection options as described in the docs and values.yaml.
See the relevant Helm template logic here.

To reply, just mention @dosu.

@Goopil Could you rephrase the issue? I struggle to understand what you think the expected state should be.
