Do you have any older versions of the JDBC driver in your CLASSPATH? 
Make sure that you only have one JDBC driver in your CLASSPATH.  If you
are using bash, you should do the following:

export CLASSPATH=/usr/share/java/postgresql.jar

And just for reference, which vendor/version of JDK or JRE are you
using?  In the past, we noticed funny things happening when mixing and
matching different versions of JDK and JRE in your environment, even if
they're from the same vendor.  We developed and tested our software on
Sun's SDK version 1.4.2.

I hope that helps.  If you have further questions, please ask.
