   3.6) What is the upgrade process for PostgreSQL?
   
-   The PostgreSQL team makes only bug fixes in minor releases, so, for
-   example, upgrading from 7.4.8 to 7.4.9 does not require a dump and
-   restore; merely stop the database server, install the updated
-   binaries, and restart the server.
-   
-   All users should upgrade to the most recent minor release as soon as
-   it is available. While every upgrade has some risk, PostgreSQL minor
-   releases are designed to fix only common bugs with the least risk. The
-   community considers not upgrading more risky that upgrading.
-   
-   Major releases (e.g. from 7.3 to 7.4) often change the internal format
-   of system tables and data files. These changes are often complex, so
-   we don't maintain backward compatibility for data files. A dump/reload
-   of the database is required for major upgrades.
