Thanks Jaime but that's not really what I meant.

I know that if a session creates a temporary table it is only visible
to that session. I'm not doing a good job of explaining this but
basically given the following results...

test=> select relname, relnamespace, reltype from pg_class where
relname = 'session_data';
relname | relnamespace | reltype
--------------+--------------+----------
session_data | 2200 | 16114367
session_data | 16120903 | 16314010
session_data | 16120709 | 16314030
session_data | 16122659 | 16314133
session_data | 16123201 | 16314285
session_data | 16124398 | 16315049
session_data | 16767 | 16315527
session_data | 16120382 | 16315818
session_data | 16125558 | 16315816
session_data | 16114413 | 16316810
session_data | 16127654 | 16317471
session_data | 16114683 | 16317551
session_data | 16118447 | 16317563
session_data | 15035529 | 16317579
(14 rows)

How can I determine if one of the above relations is a temporary
table in the current session (one of them, the first in ns 2200, is a
normal permanent table)?

Thanks,
James
