Wouldn't INHERIT and IN ROLE work?:

https://www.postgresql.org/docs/12/sql-createrole.html

INHERIT
NOINHERIT

     These clauses determine whether a role “inherits” the privileges of 
roles it is a member of. A role with the INHERIT attribute can 
automatically use whatever database privileges have been granted to all 
roles it is directly or indirectly a member of. Without INHERIT, 
membership in another role only grants the ability to SET ROLE to that 
other role; the privileges of the other role are only available after 
having done so. If not specified, INHERIT is the default.
"


"IN ROLE role_name

     The IN ROLE clause lists one or more existing roles to which the 
new role will be immediately added as a new member. (Note that there is 
no option to add the new role as an administrator; use a separate GRANT 
command to do that.)
