I have seen this message in the archive: http://archives.postgresql.org/pgsql-bugs/2010-04/msg00034.php I happened to encounter the same issue and couldn't find another post regarding it (other than the one mentioned above), let alone a solution. After some trial and error, though, I managed to find an easy solution myself and would like to document it.
This problem can be solved mrrely by setting the language explicitly to English (rather than simply Default). This can be done in File - Options - General - User Language. Afterwards, the application needs to be restarted.
