Re: Set query_id for query contained in utility statement

PREPARE test_prepare_pgss1(int, int) AS select generate_series($1, $2);
SELECT pg_stat_statements_reset() IS NOT NULL AS t;
EXECUTE test_prepare_pgss1 (1,2);
EXECUTE test_prepare_pgss1 (1,3);
SELECT toplevel, calls, query, queryid, rows FROM pg_stat_statements
ORDER BY query COLLATE "C", toplevel;
SELECT pg_stat_statements_reset() IS NOT NULL AS t;

---the above works just fine. just for demo purpose

explain(verbose) EXECUTE test_prepare_pgss1(1, 2);
explain(verbose) EXECUTE test_prepare_pgss1(1, 3);


SELECT toplevel, calls, query, queryid, rows FROM pg_stat_statements
ORDER BY query COLLATE "C", toplevel;
 toplevel | calls |                                 query
                    |       queryid        | rows

Is it possible to normalize top level utilities explain query, make
these two have the same queryid?
explain(verbose) EXECUTE test_prepare_pgss1(1, 2);
explain(verbose) EXECUTE test_prepare_pgss1(1, 3);


I guess this is a corner case.
