Here's another case that doesn't work too well:
regression=> create table u1(i int);
CREATE
regression=> insert into u1 values(1);
INSERT 150665 1
regression=> insert into u1 values(1);
INSERT 150666 1
regression=> create temp table u1(i int);
CREATE
regression=> create unique index i_u1 on u1(i);
CREATE
regression=> select * from u1; -- yup, temp table is empty
i
-
(0 rows)
regression=> drop table u1; -- drop temp table
DROP
regression=> select * from u1; -- ok, we're back to permanent u1
i
-
1
1
(2 rows)
regression=> begin;
BEGIN
regression=> create temp table u1(i int);
CREATE
regression=> create unique index i_u1 on u1(i);
ERROR: Cannot create index: 'i_u1' already exists
-- apparently, dropping a temp table doesn't drop its temp indexes?
regression=> end;
END
regression=> select * from u1;
ERROR: cannot find attribute 1 of relation pg_temp.24335.3
-- oops, what's causing this? Shouldn't the xact have been rolled back
-- due to error?
regression=> \q
-- backend coredumps on quit
Looks like indexes on temp tables need some serious work :-(
