Manage non-ascii PG errors

When PG is localized, error messages are not ascii and jobs are not postponed. Instead they are failed with a 'unicode decode error'.

Note: even if PG ```lc_messages``` is set to en_us.utf8 on a localized system, the error message prefixes (such as ```DETAILS:```) are still localized.
