Attached patch addresses these points, so should now apply cleanly agains dev.
I also changed the OID assigned to ROWS_IN and its support function.
In passing, I noticed there is one existing function that can consume and make good use of ROWS_IN’s result when used in the target list, which is row_to_json. This is good, as it makes ROWS_IN useful even outside of a change to allow results in the FROM to be pipelined. I’ve called out row_to_json specifically in the documentation change.
