I am new to Postgresql, I have installed the Postgresql 9.1.8 in my ubuntu 12.04 machine and I found 9.1.9 was released last week, can someone advise me how to upgrade pg from 9.1.8 to 9.1.9?
or, are the following commands correct for this upgrade?
apt-get update
apt-get upgrade
(os Ubuntu 12.04 64-bit, current Postgresql version is 9.1.8, target version 9.1.9)
