<p>Hello Glyn,</p><p>it's confusing, but You didn't read the manual very carefully!</p><p> </p><p>Short excerpt:</p><p>The INHERIT attribute governs inheritance of grantable privileges (that is, access privileges for<br />database objects and role memberships). It does not apply to the special role attributes set by CREATE<br />ROLE and ALTER ROLE. For example, being a member of a role with CREATEDB privilege does not<br />immediately grant the ability to create databases, even if INHERIT is set; it would be necessary to<br />become that role via SET ROLE before creating a database.</p><p> </p><p>bye...</p><p>Ludwig</p><p> </p><p> </p>
