wikipedia:Database schema are analogous to directories at the operating system level, except that schemas cannot be nested. [1] Typical schemas usage scenarios [2]:
- 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.
Example
Grant examples on schemas:
GRANT USAGE ON ALL SEQUENCES IN SCHEMA your_schema TO mygrp;
[3]GRANT USAGE ON SCHEMA your_schema TO GROUP your_group;
- Show/List schemas:
select nspname from pg_catalog.pg_namespace;
select schema_name from information_schema.schemata;

PostgreSQL: pg_catalog
