9.1 to 9.2 upgrade surprises

So I upgraded our Postgresql boxes from 9.1 to 9.2.
Everything went pretty smooth except for a few glitches , but now all's good.

After the upgrade I dropped the original 9.1 cluster:

$ sudo pg_dropcluster 9.1.old main

After this I correctly ended up with just newly installed 9.2 cluster:

~ $ sudo pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
9.2 main 5432 online postgres /var/lib/postgresql/9.2/main /var/log/postgresql/postgresql-9.2-main.log
~ $

Now, when I try to restart postgresql I get the following:
~ $ /etc/init.d/postgresql restart
* Restarting PostgreSQL 9.1 database server [ OK ]
* Restarting PostgreSQL 9.2 database server [ OK ]
~ $

W00T ?! 9.1 ? I thought I had removed that one....Now, I'm guessing that has to do with this ?

$
~ $ ls -l /etc/postgresql/
total 8
drwxr-xr-x 3 postgres postgres 4096 Jan 1 16:01 9.1
drwxr-xr-x 3 postgres postgres 4096 Dec 30 18:21 9.2
~ $

Upgrade process made a backup of all 9.1 configuration files and pg_dropcluster didn't remove it and init scripts stil somehow tries to restart it ?

NoW, the weirdest thing. I tried to remove 9.1 package as I dont need those...these are ALL PG packages installed:

~ $ dpkg -l|grep postgres
ii check-postgres 2.18.0-1 script for monitoring PostgreSQL databases
ii pgdg-keyring 2013.2 keyring for apt.postgresql.org

ii postgresql-server-dev-9.2 9.2.6-1.pgdg12.4+1 development files for PostgreSQL 9.2 server-side programming
~ $

So I ran this and got the BIGGEST SURPRISE so far - LOOKS LIKE REMOVAL OF 9.1 PACKAGES TRIES TO INSTALL 9.3 ones ??? UHH
I have INDEED aborted the uninstall straight away and would like some PG gurus opinion on this:

$ sudo apt-get remove --purge postgresql-9.1 postgresql-client-9.1 postgresql-contrib-9.1 postgresql-server-dev-9.1
