I wonder if we should go with an SQL query now (no new API needed) and then add a GUC once we decide on how extensions can register that they are generating the query id, so the GUC can report the generating source, not just a boolean. The core server can also register as the source.
I have no problem with it. This is an internal feature and can be enhanced (fixed) in time without problems.
