I tested it. all normally works fine. only 1 corner case:
set pg_stat_statements.track = 'all';
drop table if Exists cp_test;
CREATE TABLE cp_test (a int, b text);
CREATE or REPLACE PROCEDURE ptest1(x text) LANGUAGE SQL AS $$ INSERT
INTO cp_test VALUES (1, x); $$;
CREATE or REPLACE PROCEDURE ptest3(y text)
LANGUAGE SQL
AS $$
CALL ptest1(y);
CALL ptest1($1);
$$;
SELECT pg_stat_statements_reset();
CALL ptest3('b');
SELECT calls, toplevel, rows, query FROM pg_stat_statements ORDER BY
query COLLATE "C";
returns:
calls | toplevel | rows | query
-------+----------+------+------------------------------------
1 | t | 0 | CALL ptest3($1)
2 | f | 2 | INSERT INTO cp_test VALUES ($2, x)
1 | t | 1 | SELECT pg_stat_statements_reset()
here, the intermediate CALL part is optimized away. or should I expect
CALL ptest1($1) also in pg_stat_statements?
