Temp tables are curious creatures....

Appears psql needs to know how to differentiate between it's own temp
tables and those of another connection.  On the plus side, this takes
care of a TODO item to add temp table listings to psql.

Connection 1:

template1=# create temp table junk(col1 int4);
CREATE
template1=# select * from junk;col1 
------
(0 rows)


Connection 2:
template1=# \d List of relationsName | Type  | Owner 
------+-------+-------junk | table | rbt
(1 row)

template1=# select * from junk;
ERROR:  Relation "junk" does not exist

template1=# create temp table junk (col4 text);
CREATE
 List of relationsName | Type  | Owner 
------+-------+-------junk | table | rbtjunk | table | rbt
