I tried to execute the first statement on the database directly and, in fact, it does not like it :

select * from statusmail where idle='0' and idMailable='14' and ( false or idStatus=' ' or idEvent='9' )

It doesn't like the space on the "idStatus" field, since it is expecting a numeric.

By the way, I am running on a PostgreSQL v8.4.20.
