52.56. pg_tablespace #

   The catalog pg_tablespace 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 cluster: there is only one copy of pg_tablespace per
   cluster, not one per database.
