如何从 Ubuntu 13.04 中完全删除 postgresql？

Question

我试过了

sudo apt-get purge postgresql
sudo apt-get autoremove postgresql

和

sudo apt-get --purge remove postgresql

但在这之后dpkg -l | grep postgres给了我：

pi  postgresql-9.1                            9.1.11-0ubuntu0.13.04                    amd64        object-relational SQL database, version 9.1 server
pi  postgresql-client-9.1                     9.1.11-0ubuntu0.13.04                    amd64        front-end programs for PostgreSQL 9.1
ii  postgresql-client-common                  140                                      all          manager for multiple PostgreSQL client versions
ii  postgresql-common                         140                                      all          PostgreSQL database-cluster manager
ii  postgresql-contrib                        9.1+140                                  all          additional facilities for PostgreSQL (supported version)
ii  postgresql-contrib-9.1                    9.1.11-0ubuntu0.13.04                    amd64        additional facilities for PostgreSQL
ii  postgresql-doc-9.1                        9.1.11-0ubuntu0.13.04                    all          documentation for the PostgreSQL database management system

如果我尝试开始psql：

psql: could not connect to server: No such file or directory
    Is the server running locally and accepting
    connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

所以，如我所见，安装了 postgresql。
