The following documentation comment has been logged on the website:

Description:
Could you provide additional information about pg_ctlcluster command? On
postgrsql 13 clusters there is no pg_ctl reload.
So we should not use `pg_ctl reload` instead eg `pg_ctlcluster 13 main
reload` (after listing clusters with `pg_lsclusters`).
