execute/perform and FOUND

Hi,

I am utterly confused now. Running the attached script on Debian:

postgresql:
Installiert:7.5.21
Mögliche Pakete:7.5.21
Versions-Tabelle:
*** 7.5.21 0
990 ftp://ftp.gwdg.de testing/main Packages
100 /var/lib/dpkg/status
7.4.7-6sarge3 0
500 ftp://ftp.gwdg.de stable/main Packages
500 ftp://ftp.de.debian.org stable/main Packages
7.4.7-6sarge2 0
500 http://security.debian.org stable/updates/main Packages

gives the result below. It seems inconsistent to me with
regard to the FOUND variable. I would expect FOUND to always
be false regardless of whether I use EXECUTE or PERFORM. I
certainly do not expect it to be true for the third EXECUTE
even assuming that PERFORM may have a bug. What is it that I
am missing out on here ?

BEGIN
CREATE TABLE
CREATE FUNCTION
select * from test;
fk_item
---------
(0 Zeilen)

select test();
psql:00-test.sql:33: NOTICE: running: select 1 from test where fk_item=1324314
psql:00-test.sql:33: NOTICE: found (execute 1): f
psql:00-test.sql:33: NOTICE: found (execute 2): f
psql:00-test.sql:33: NOTICE: found (perform): t
psql:00-test.sql:33: NOTICE: found (execute 3): t
test
------
t
(1 Zeile)

rollback;
ROLLBACK

Thanks,
Karsten
