Correction for: "21.6. Tablespaces"

Hi

The last paragraph on the page "21.6. Tablespaces":

 "and after you restart the server, update the pg_tablespace catalog
with the new locations"

is partially inaccurate as of PostgreSQL 9.2, as the spclocation
column which is meant
here was removed in 9.2 [2]).

Patch attached; I also added a link to the "pg_tablespace" page.
