PostgreSQL version: 7.4.7 / 8.0.1
Operating system: Linux x86
Description: Temp table isn't deleted at the end of a transaction /
ON COMMIT DROP has no effect
Details:
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
