Development Versions: [devel](https://www.postgresql.org/docs/devel/view-pg-user-mappings.html "PostgreSQL devel - 53.36. pg_user_mappings")

The view `pg_user_mappings` provides access to information about user mappings. This is essentially a publicly readable view of [`pg_user_mapping`](https://www.postgresql.org/docs/current/catalog-pg-user-mapping.html "52.65. pg_user_mapping") that leaves out the options field if the user has no rights to use it.

-   current user is the server owner and mapping is for `PUBLIC`
    
-   current user is a superuser
