Why not to use auto_explain module?

postgres=# LOAD 'auto_explain';
LOAD
postgres=# SET auto_explain.log_min_duration = 0;
SET
postgres=# SET auto_explain.log_nested_statements = on;
SET
postgres=# SET auto_explain.log_analyze = on;
SET
postgres=# SET auto_explain.log_level = 'NOTICE';
SET
postgres=# DO $$BEGIN FOR i IN 112 .. 113 LOOP PERFORM * FROM pg_class
WHERE oid = i::oid; END LOOP; END;$$;
