Maybe something along those lines:

    SELECT spcname AS "Name",
      pg_catalog.pg_get_userbyid(spcowner) AS "Owner",
      pg_catalog.pg_tablespace_location(t.oid) AS "Location",
      pg_catalog.array_to_string(spcacl, E'\n') AS "Access privileges",
      spcoptions AS "Options",
      pg_catalog.pg_size_pretty(pg_catalog.pg_tablespace_size(t.oid)) AS "Size",
      pg_catalog.shobj_description(t.oid, 'pg_tablespace') AS "Description"
    FROM pg_catalog.pg_tablespace t
    LEFT JOIN pg_catalog.pg_database d
      ON datname = pg_catalog.current_database()
      AND dattablespace = t.oid
    WHERE pg_catalog.has_tablespace_privilege(t.oid, 'CREATE')
      OR pg_has_role('pg_read_all_stats', 'USAGE')
      OR dattablespace IS NOT NULL -- is default tablespace?
    ORDER BY 1;
