There really were no changes to the driver. 1002 was mistakenly created using java 1.7 and pushed to maven central. As such it was not useable by java 1.6 1003 is really just a recompile with 1.6
Thanks for reminding me about the timer fix. I will see if a patch will just apply to 9.2
It seems new PostgreSQL JDBC Driver(9.2-1003) is released. But I can not find waht change has been done to new driver, because no Changelog about new driver is download site. http://jdbc.postgresql.org/changes.html
