    postgresql_default.conf: Make sure the "disk_io" query does not return NULLs.
    
    Starting with some version between 8.3.3 and 8.3.6, pg_statio_*_tables returns
    NULL instead of 0 for statistics if no instance of the appropriate relation
    exists. PQgetvalue() returns an empty string in that case which would then
    result in error messages when udb_result_submit() tries to convert that to a
    number.
    
    Now, the "disk_io" query uses PostgreSQL's coalesce() function to make sure 0
    is returned instead of NULL.
