如何在 CentOS 上将 Postgres 9.2.2 升级到 9.2.3

将 Postgres 升级到 9.2.3 的正确方法是什么？

（如果可能的话，我宁愿不必删除/恢复我的数据库。）

# 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.
