i'm trying to fix a problem related to the patch Albert sent in
october (Tablespace for temporary objects and sort files)
http://archives.postgresql.org/pgsql-patches/2006-10/msg00141.php
http://archives.postgresql.org/pgsql-patches/2007-01/msg00063.php

after reviewing this i notice this will not use different tablespaces
in the case of having various connections all with just one temp
table:
http://archives.postgresql.org/pgsql-patches/2007-01/msg00188.php

what i'm trying to do it is share what's the next_temp_tablespace to use...
the other way to do this is as you say using tables, but i don't think
this is a good idea in this case...

comments?
