3.7.6 Usage Patterns
Schemas can be used to organize your data in many ways. There are a few usage patterns that are recommended and are easily supported by the default configuration:
- If you do not create any schemas then all users access the public schema implicitly. This simulates the situation where schemas are not available at all. This setup is mainly recommended when there is only a single user or a few cooperating users in a database. This setup also allows smooth transition from the non-schema-aware world.
You can create a schema for each user with the same name as
that user. Recall that the default search path starts with
$user, which resolves to the user name. Therefore, if each user has a separate schema, they access their own schemas by default. If you use this setup then you might also want to revoke access to the public schema (or drop it altogether), so users are truly constrained to their own schemas.
- To install shared applications (tables to be used by everyone, additional functions provided by third parties, etc.), put them into separate schemas. Remember to grant appropriate privileges to allow the other users to access them. Users can then refer to these additional objects by qualifying the names with a schema name, or they can put the additional schemas into their search path, as they choose.
