Make sure you are running the latest available minor release for your major version before reporting a bug. The current list of supported versions is 9.4.4, 9.3.9, 9.2.13, 9.1.18, 9.0.22.
But the "PostgreSQL version" drop down lists all of the non-latest-available minor releases. Shouldn't the drop down remove all the minor versions for which people have been dis-invited to report bugs?
