Database schemas are analogous to directories at the operating system level, except that schemas cannot be nested. [1]


Typical schemas usage scenarios:

  • To allow many users to use one database without interfering with each other.
  • To organize database objects into logical groups to make them more manageable.
  • Third-party applications can be put into separate schemas so they do not collide with the names of other objects.


PostgreSQL:

  • Show/List schemas: select nspname from pg_catalog.pg_namespace;[2]
