In general this looks good. Some nitpicks:
+/*
+ * Ownership check for a role (specified by OID)
+ */
+bool
+pg_role_ownercheck(Oid role_oid, Oid roleid)
This is a bit confusing. Let's rename these params so it's clear which
is the owner and which the owned role.
+ * Note: In versions prior to PostgreSQL version 15, roles did not have
owners
+ * per se; instead we used this test in places where an ownership-like
+ * permissions test was needed for a role.
No need to talk about what we used to do. People who want to know can
look back at older branches.
+bool
+has_rolinherit_privilege(Oid roleid)
+{
This and similar functions should have header comments.
+ /* Owners of roles have every privilge the owned role has */
s/privlge/privilege/
+CREATE ROLE regress_role_1 CREATEDB CREATEROLE REPLICATION BYPASSRLS;
I don't really like this business of just numbering large numbers of
roles in the tests. Let's give them more meaningful names.
+ Role owners can change any of these settings on roles they own except
I would say "on roles they directly or indirectly own", here and
similarly in one or two other places.
...
I will probably do one or two more passes over the patches, but as I say
in general they look fairly good.
