I think you're asking to add introspection data here:

https://github.com/graphile/graphile-engine/blob/b715f6d1be7dd19e39830b4329fa3c758e5ae91b/packages/graphile-build-pg/src/plugins/makeProcField.js#L635

I'd love a PR for that :+1:

[id3nom]

Yes that's what I mean, I successfully have expanded the 'payloadTypeScope' but the 'fieldScope' expansion doesn't work, maybe you can give me a hint on that.

If I find a way to do it I will post a PR with the changes.

[benjie]

Probably just adding

            ...payloadTypeScope

after the above line would suffice? If that was raised as a PR I'd also want the variable renamed since it's not just used in the payload any more.

the 'fieldScope' expansion doesn't work

I don't really follow. What do you mean by "doesn't work"?

[id3nom]

What I mean is that expanding 'payloadTypeScope' give introspection data on the PostgreSQL function but I'm unable to get introspection data on the arguments.

[benjie]

Arguments don't have separate introspection; they're part of the function from pg_proc: https://github.com/graphile/graphile-engine/blob/726c210ae6f559c132f859fed18dc031a2a2cb1c/packages/graphile-build-pg/src/plugins/introspectionQuery.js#L75-L79
