timeout funcionality for postgres?

[mischa.z]

Does anyone know if the timeout funcionality for ibatis > 2.2.0 is 
supposed work with the postgres jdbc drivers (8.2-505 JDBC 4)?
It doesn't work for me and I wonder if it's just a configuration issue.
All I did was specifying the global timeout in
<settings defaultStatementTimeout="2" />
and in the statement itself
<statement ... timeout="2">.
Thanks,
Mischa
