<H3 id="item3.6">3.6) What is the upgrade process for PostgreSQL?</H3>
<P>The PostgreSQL team only adds bug fixes to minor releases. All
users should upgrade to the most recent minor release as soon as
possible. While upgrades always have some risk, PostgreSQL minor
releases fix only frequently-encountered, security, and data corruption
bugs, to reduce the risk of upgrading. The community considers
<i>not</i> upgrading more risky than upgrading.</P>
<P>PostgreSQL major releases include new features and occur roughly
once every year. A major release is numbered by increasing either
the first or second part of the version number, e.g. 8.1 to 8.2.
<P>Upgrading to a minor release, e.g. 8.1.5 to 8.1.6, does not does
not require a dump and restore; merely stop the database server,
install the updated binaries, and restart the server.</P>
<P>Major releases usually 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.</P>

<P>Minor releases are numbered by increasing the third part of the

bug fixes to minor releases. All users should upgrade to the most
