I don't have any in mind ...

Yes they should, but they aren't yet (event with CMDTAG_SELECT added)

Note that implicit cursors behave the same way ;o(

postgres=# do $$ declare i integer; begin for i in (select 1 ) loop null;
end loop;end; $$;
DO
postgres=# select calls,query,rows from pg_stat_statements;
 calls |                                      query                                     
| rows
-------+---------------------------------------------------------------------------------+------
     1 | select pg_stat_statements_reset()                                              
|    1
     1 | (select $1 )                                                                   
|    0
     1 | do $$ declare i integer; begin for i in (select 1 ) loop null; end
loop;end; $$ |    0
(3 rows)
