BUG #3239: French translation error

The following bug has been logged online:

Bug reference:      3239

PostgreSQL version: 8.2.3
Operating system:   Linux
Description:        French translation error
Details:

English error message is explicit :

ERROR:  subquery in FROM may not refer to other relations of same query
level

French error message is wrong :

ERREUR:  La sous-requête du FROM pourrait ne pas référer à une autre
relation dans le même niveau de la requête

"subquery may not refer" can mean 2 things :
- it is forbidden for subquery to refer to ... (right in this context)
- probably does not refer to (incorrect, this is the french version)

It sounds like a MySQL error message (ie . "There is an error somewhere in
your query." )

Fix : use "cannot" instead of "may not" so translators have no doubts.
Review translations of modified strings.

Have a nice day !
