# 52.54. 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.
