   3    The catalog <code class="structname">pg_tablespace</code> stores information
   4    about the available tablespaces.  Tables can be placed in particular
   5    tablespaces to aid administration of disk layout.

   8    is shared across all databases of a cluster: there is only one
   9    copy of <code class="structname">pg_tablespace</code> per cluster, not
  10    one per database.
