[GENERAL] Not possible to compare regrole in a view query?

I have this simple view definition:

CREATE TEMP VIEW user_schema AS
    SELECT nspname AS name FROM pg_namespace
    WHERE nspname = 'public' OR nspowner = ‘rolename'::regrole;

But it fails to create the view by complaining: constant of the type "regrole" cannot be used here

If I run the query directly, I get the correct result.

Does that mean I can’t compare role name this way in view? Should I use join to work around it?

Thanks.
