[BUGS] Possible temp table bug in PostgreSQL 7.4.7 / 8.0.1

[Oliver Siegmar]

Hello,

I've probably found a temp table bug in PostgreSQL (tested with 7.4.7 and 
8.0.1 on Linux x86).


Here's a demonstration of the bug:

CREATE FUNCTION testfunction()
RETURNS void
AS '
    BEGIN
        CREATE TEMP TABLE testtable (field int4) ON COMMIT DROP;
        
        INSERT INTO testtable (field) VALUES (1);
        
        -- DROP TABLE testtable;

        RETURN;
    END;
' LANGUAGE 'plpgsql';


database=# SELECT testfunction();

 testfunction
--------------

(1 row)

database=# SELECT testfunction();
ERROR:  relation with OID 29308882 does not exist
CONTEXT:  SQL statement "INSERT INTO testtable (field) VALUES (1)"
PL/pgSQL function "testfunction" line 4 at SQL statement


No transaction has been started manually.

If I drop the temporary testtable manually within the PL/pgSQL function, 
everything runs fine. Bug or feature? ;-)


Cheers,
Oliver
