53.56. pg_tablespace #
目录 pg_tablespace 存储有关可用表空间的信息。可以将表放置在特定表空间中以帮助管理磁盘布局。
The catalog pg_tablespace stores information about the available tablespaces. Tables can be placed in particular tablespaces to aid administration of disk layout.
与大多数系统目录不同，pg_tablespace 在集群的所有数据库之间共享：每个集群只有一个 pg_tablespace 副本，而不是每个数据库一个。
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.
