Error when deleting menu item (with PostgreSQL as database backend)

Create an arbitrary menu item and try do delete it again.

The following SQL query will performed:

query: DELETE FROM localizertranslation WHERE (object_name='menu' || object_name='menu_item') AND object_key='137' in /var/www/html/drupal-5.7/includes/database.pgsql.inc on line 144.

Using PostgreSQL as database backend, you will get an error:

pg_query() [function.pg-query]: Query failed: FEHLER: Operator existiert nicht: character varying = boolean at character 52 HINT: Kein Operator stimmt mit dem angegebenen Namen und den Argumenttypen überein. Sie müssen möglicherweise ausdrückliche Typumwandlungen hinzufügen. in /var/www/html/drupal-5.7/includes/database.pgsql.inc on line 125.

Reason: The logical operator || is known to MySQL, but not to PostgreSQL
Fix: Use the logical operator OR instead of || which ist understood by both PostgreSQL and MySQL.
Patch attached.
