Dear S. M.,

Even if a role (user) personally doesn't have any permissions to access
a schema, memerships in other roles (groups) may allow access.

Check memberships and never, ever grant permissions to individual user
roles, but only to non-login (group) roles. This minimises the number of
grants and enhances clarity of permissions.

Kind Regards,

Holgger
