Как обновить Postgres 9.2.2 до 9.2.3 в системе CentOS

Как правильно обновить Postgres до 9.2.3?

(Я бы предпочел не удалять / восстанавливать свои базы данных, если это возможно.)

# rpm -qi postgresql92-server

Summary     : The programs needed to create and run a PostgreSQL server
Description :
The postgresql92-server package includes the programs needed to create
and run a PostgreSQL server, which will in turn allow you to create
and maintain PostgreSQL databases.  PostgreSQL is an advanced
Object-Relational database management system (DBMS) that supports
almost all SQL constructs (including transactions, subselects and
user-defined types and functions). You should install
postgresql92-server if you want to create and maintain your own
PostgreSQL databases and/or your own PostgreSQL server. You also need
to install the postgresql package.

Версия CentOS:

# cat /etc/redhat-release
CentOS release 6.2 (Final)
