Awhile back, someone went around and made sure that all the contrib modules had uninstall scripts, but most of the new contributions since then don't have 'em: adminpack hstore pg_freespacemap pgrowlocks sslinfo all seem to need one. Also, I tested a few of the existing uninstall scripts in passing while fixing the contains/contained mess, and two out of four were broken (failed to remove everything installed by the module, as shown by getting errors if you then try to reinstall it). Seems like this area needs more attention ... anyone want to work on it?
