Hi, Tom
Thnaks for you reply; I don't need timezone in this application so it's
okay.
However, I've been trying to change the table on 7.1.3 to get ready for
the swap but there's no timestamp without timezone on 7.1.3;
do I really have to edit the dump before reloading, ISTM that it's the
best way to generate errors...
