A while back I noted in this thread that some people were having issues with timestamps and infinity.
I have been using a modified version of the 7.4 driver for some time now and have had no real issues with these modifications. The modifications that I made involve adding two additional classes to the driver package. They are simple classes that extend java.sql.Date and java.sql.Timestamp. In my opinion this solution is much more elegant than relying on some magic number used in the underlying java.util.Date class.
The main beauty of these modification are that you do not need to rely any PostgreSQL driver specifics to detect values of infinity, and on a similar note the driver doesn't have to rely on its own implementations of infinity, it can handle third party implementations.
If anyone is interested in these modification I will post them on this thread, just ask.
