pg_stat_statements: rows not updated for CREATE TABLE AS SELECT statements

Hello,
it seems that column "rows" is not updated after CREATE TABLE AS SELECT
statements.

pg13devel (snapshot 2020-03-14)
postgres=# select name,setting from pg_settings where name like 'pg_stat%';
name | setting
----------------------------------+---------
pg_stat_statements.max | 5000
pg_stat_statements.save | on
pg_stat_statements.track | all
pg_stat_statements.track_utility | on
(4 rows)

postgres=# select pg_stat_statements_reset();
pg_stat_statements_reset
--------------------------

(1 row)

postgres=# create table ctas as select * from pg_class;
SELECT 386
postgres=# select query,calls,rows from pg_stat_statements where query like
'create table ctas%';
query | calls | rows
---------------------------------------------+-------+------
create table ctas as select * from pg_class | 1 | 0
(1 row)

after modifying the following line in pg_stat_statements.c

rows = (qc && qc->commandTag == CMDTAG_COPY) ? qc->nprocessed : 0;
into
rows = (qc && (qc->commandTag == CMDTAG_COPY
|| qc->commandTag == CMDTAG_SELECT)
) ? qc->nprocessed : 0;

column rows seems properly updated.

What do you think about that fix ?
Thanks in advance
Regards
PAscal
