pg_tablespace

The pg_tablespace system catalog table stores information about the available tablespaces. Tables can be placed in particular tablespaces to aid administration of disk layout. Unlike most system catalogs, pg_tablespace is shared across all databases of a OushuDB system: there is only one copy of pg_tablespace per system, not one per database.
