Comment 10 for bug 1966506

I see that my current version is 10.22:

$ sudo -u postgres psql -c "SELECT version();"
[sudo] password for edvinas:
Sorry, try again.
[sudo] password for edvinas:
                                                               version
--------------------------------------------------------------------------------------------------------------------------------------
 PostgreSQL 10.22 (Ubuntu 10.22-0ubuntu0.18.04.1) on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0, 64-bit
(1 row)

So probably I should go and execute all the steps in https://discourse.maas.io/t/upgrading-postgresql-to-version-12/5913 and then verify that this command "sudo -u postgres psql -c "SELECT version();"" shows correct version?
