Postgresql 7.4.3/8.2.4 out of memory

Dear all,

With the below transaction we got an out of memory error.

BEGIN;
ANALYZE referenceAuthorLnkTemp;

INSERT INTO referenceAuthor (author)
SELECT DISTINCT ON (author) author
FROM referenceAuthorLnkTemp;

ANALYZE referenceAuthor;

UPDATE referenceAuthorLnkTemp
SET idAuthor = referenceAuthor.id
FROM referenceAuthor
WHERE referenceAuthorLnkTemp.author = referenceAuthor.author;

INSERT INTO referenceAuthorLnk (idAuthor, idReference)
SELECT DISTINCT ON (referenceAuthorLnkTemp.idAuthor,
referenceAuthorLnkTemp.idReference) referenceAuthorLnkTemp.idAuthor,
referenceAuthorLnkTemp.idReference
FROM referenceAuthorLnkTemp;
END;

This transaction belongs to a file with many other transactions
executed through a java program and JDBC
(postgresql-8.2-505.jdbc3.jar).
Launching this transaction by hand in psql works.

Server has 8GB of RAM and OS is RHEL 3 update 6.
Linux 2.4.21-37.ELsmp #1 SMP Wed Sep 7 13:28:55 EDT 2005 i686 i686 i386
GNU/Linux

The number of rows in tables are:

43360793 tuples referenceauthorlnktemp
43360791 tuples referenceauthorlnk
56990 tuples referenceauthor

Thanks for help.
