I'm replying to myself to let you all know that this bug is fixed now. The newest 7.3 JDBC drivers from jdbc.postgresql.org contain the patch.

I've discovered a fairly minor bug in the JDBC driver that ships with PostgreSQL 7.3. It causes a bogus ObjectModifiedException in test TC20 (TypeHandling) of the JDO test suite, so it is possible that it could impact some castor users. That's why I'm mentioning it here.
The message I sent to the pgsql-jdbc list hasn't made it into their archive yet, so here's a summary of the bug: when you retrieve a TIMESTAMP field from a PostgreSQL 7.3 database and it contains fractional second information, the fractional second information will be wrong if there is more than one decimal-place's worth. The problem this caused with the JDO tests was that the cached version of an affected timestamp field was always out-of-sync with the actual database, leading to the aforementioned ObjectModifiedException.
Anyway, all the details are in my pgsql-jdbc post, so if you are interested, wait for a while and it should show up here: http://archives.postgresql.org/pgsql-jdbc/2003-01/index.php. Or if you are in a hurry, you can e-mail me and I'll forward you the > message.
