is it possible to get `request_id` in postgres function session variables?

I'm trying to capture `x-request-id` in postgres trigger for debug and audit purpose. Looks like only header starts with `x-hasura-*` will expose to session variable `CURRENT_SETTING('hasura.user', 't')`.

Is it possible to get `x-request-id` in postgres function session variables?

https://hasura.io/docs/latest/graphql/core/deployment/logging.html#log-structure-and-metrics

Start with the linked logging documentation and the PostgreSQL trigger/session-variable context described in the issue. Trace how request headers are exposed through CURRENT_SETTING('hasura.user', 't') and determine whether x-request-id is included. Done means the supported behavior is established and the issue is resolved with corresponding documentation or implementation guidance.
