postgres jar in oozie.war

[bowen zhang]

Hi oozie developers,
I recently discovered that oozie.war is always packaged with postgresql 9 jars 
after build. What if the customers want to run postgres 8 jars during the setup 
process? Or OpenJPA only works with Postgresql 9. I propose to eliminate the 
postgresql dependency in the pom.xml for the build process.
Any thoughts?
