There is already something very similar to what you are describing:
https://www.psycopg.org/docs/cursor.html
Each cursor has its description, which consists of the column descriptions. Basically, it's like doing \d on a cursor. Unfortunately, it's not interactive, one has to do some pythong programming in order do to that. Unfortunately, it is not possible to just "describe the cursor", the description becomes available after the "execute" call. Hopefully, I understood you correctly.
