wikipedia:Database schema are analogous to directories at the operating system level, except that schemas cannot be nested. [1] Typical schemas usage scenarios [2]:

  • Third-party applications can be put into separate schemas so they do not collide with the names of other objects.
public or default

Examples[edit]

Grant examples on schemas:

PostgreSQL: pg_catalog and public.


GRANT SELECT ON ALL TABLES IN SCHEMA public TO xxx;
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT ON TABLES TO xxx;
