Connecting to external Postgres with Postgraphile API

Hi. The plugin works great as far as to querying in the Wp DB, but I would like to use it to talk with an external Postgres DB with a PostGraphile API.

This seems to imply modifying the plugin’s schema to include the necessary fields and types for interacting with the PostGraphile API. It probably involves creating custom resolvers and modifying the schema using the register_graphql_fields and register_graphql_object_type functions provided by the WPGraphQL plugin (says ChatGPT).

Or are there other ways?

cheers, Karl
