Most likely because the DB is already being used in production. I ran
into this problem when upgrading our DB admin upgraded our server from
7.1 to 7.2, without letting us know.
We upgraded the driver to 7.2 and it worked, but I really cursed
whoever thought that changing the default behaviour of a timestamp
column was a good idea.
It's a PITA, but I think your best bet is to make a full ASCII dump of
your DB, replace 'timestamp' with 'timestamp (0)' and recreate it.
Good luck, and let us know of the outcome.
