Subject: [PATCH] Fix inaccurate description of tablespace.
Currently we don't need to update the pg_tablespace catalog
after redefining the symbolic links to the tablespaces
because pg_tablespace.spclocation column was removed in
PostgreSQL 9.2.
Back patch to 9.2 where pg_tablespace.spclocation was removed.
Ian Barwick, with minor change by me.
