Last year with the revisions to CREATEROLE I decided that having a view that allowed one to more readily see the membership graph of their cluster would be useful. I originally tried to write something up for psql but decided that was impractical given its requirements. Therefore, I put together a pseudo-extension for this. I've finally decided it is time to share it with the world. Since no one but myself has seen it I still consider it beta. At some point I intend to put out an announcement and a bit more formality around its release but was hoping to get some feedback first. So I share it here. For more details please check out the README file.
