It would be good to have a karaf feature for the postgresql JDBC driver #1552
I have manually created a postgresql jdbc driver karaf feature, because that gives smoother loading and unloading when I have more than one webapp using the postgresql jdbc driver.
It would be nice ifthe postgresql driver provided its own karaf feature. It's possible to piggyback the feature creation on the maven build process, using the karaf-maven-plugin and attach the feature artifacts to the deployed maven resources.
If there is interest in this, I can create a pull request.
