Обсуждение: postgres7.2.1 upgrading

http://www.ca.postgresql.org/sitess.html
says that:
The current version of PostgreSQL is 7.2.1. 
NOTE: An initdb will only be required if upgrading from pre 7.2
So, if my current version is 7.2.0 and I want upgrade it to 
7.2.1, what file should I download in order to get 'intidb'? 
if only the 'initdb' is required,
then what is the upgrade procedure?
I don't need to install whole 7.2.1 at all, do I.
my guess is that:
1.shutdown the db;
2.copy initdb of 7.2.1 to the location of initdb of 7.2.0;
3.re_intialize db by running initdb;
4.re_start postmaster.

However, no documentation says that.
Anybody can tell me?


Thanks!

You do not need to do anything special.  Just install the new version of
postgres over your existing version (making a backup dump of your data
first, of course).  7.2.0 is the same as 7.2, it's not 'pre 7.2'.
