Shut down the database server, replace the symbolic link in
data/pg_tblspc to the new location, and start the server again. The
location is also stored in pg_tablespace catalog; you'll need to fix it
with "UPDATE pg_tablespace SET spclocation ='/someotherdir/xyz_tbl'
WHERE spcname='xyz_tbl'", or pg_dumpall will still show the old location.
