Specifically, that is what you'd get from

alter system set shared_preload_libraries =3D 'auth_permission_dialog,pg_s=
tat_statements';

Correct syntax is

alter system set shared_preload_libraries =3D auth_permission_dialog,pg_st=
at_statements;

You could quote the individual list items if you felt a need to:

alter system set shared_preload_libraries =3D 'auth_permission_dialog', 'p=
g_stat_statements';

but as-is you wrote a single list item that happens to contain a
comma.
