Storing and retreiving infinity timestamp values from postgres database

I have read some posts on this mailinglist concerning the infinity value
of the timestamp data type, where it was stated that an exception is
thrown when one attempts to read infinity value. Now, on the postgresql
jdbc there is an entry in TODO list wich mentions adding handling of
'infinity' values to the jdbc documentation.

Is it possible for someone to post some code here for reading/storing
infinity timestamp values to and from postgres database?

I'm using postgres 8.1 with latest JDBC drivers, and from the postgres
JDBC web page can be concluded that the infinity support has been added
to the driver.

See attached.  We use special constants to indicate infinity because Java 
has no equivalent.  Looking at this test output, the displayed value of 
our negative infinity value looks a little suspect and I suspect there's 
something timezone dependent going on there.  Any change to that shouldn't 
affect your code, just the constants value.
