It seems to be a broken view not security risk in 7.2.1

backend 1:

hannu=# create temp table tmp_t1( i int);
CREATE
hannu=# create view tmp_v1 as select * from tmp_t1;
CREATE
hannu=# select * from tmp_v1;i 
---
(0 rows)


backend 2:

hannu=# select * from tmp_v1;
ERROR:  Relation "tmp_t1" does not exist
hannu=# create temp table tmp_t1( i int);
CREATE
hannu=# select * from tmp_v1;
ERROR:  Relation "tmp_t1" with OID 34281 no longer exists
