While the permanent redirect will fix this over the course of time, it is still better that we do not reference the old path from pgweb.

<h1>Versioning Policy <i class="fas fa-code-branch"></i></h1>
|

|
|
<p>
|
|
The PostgreSQL Global Development Group releases a new major version containing
|
|
new features about once a year. Each major version receives bug fixes and, if
|
|
need be, <a href="/support/security/">security</a> fixes that are released at
|
|
least once every three months in what we call a "minor release." For more
|
|
information on the minor release schedule, you can view the
|
|
<a href="/developer/roadmap/">minor release roadmap</a>.
|
|
<p>
|
|
|
|
<p>
|
|
If the release team determines that a critical bug or security fix is too
|
|
important to wait until the regularly scheduled minor release, it may make
|
|
a release available outside of the minor release roadmap.
|
|
</p>
|
|
|
|
<p>
|
|
The PostgreSQL Global Development Group supports a major version for 5 years
|
|
after its initial release. After its five year anniversary, a major version will
|
|
have one last minor release containing any fixes and will be considered
|
|
end-of-life (EOL) and no longer supported.
|
|
</p>
|
|

<h2>Version Numbering</h2>
|
|
|
|
<p>
|
|
Starting with PostgreSQL 10, a major version is indicated by increasing the
|
|
first part of the version, e.g. 10 to 11. Before PostgreSQL 10, a major version
|
|
was indicated by increasing either the first or second part of the version
|
|
number, e.g. 9.5 to 9.6.
|
|
</p>
|
|
|
|
<p>
|
|
Minor releases are numbered by increasing the last part of the version number.
|
|
Beginning with PostgreSQL 10, this is the second part of the version number,
|
|
e.g. 10.0 to 10.1; for older versions this is the third part of the version
|
|
number, e.g. 9.5.3 to 9.5.4.
|
|
</p>
|
|
|
|
<h2>Upgrading</h2>
|
|
|
|
<p>
|
|
<strong>
|
|
We always recommend that all users run the latest available minor
|
|
release for whatever major version is in use.
|
|
</strong>
|
|
</p>
|
|
|
|
<p>
|
|
Major versions usually change the internal format of system tables and data
|
|
files. These changes are often complex, so we do not maintain backward
|
|
compatibility of all stored data. A dump/reload of the database or use of the
|
|
<a href="/docs/current/pgupgrade.html">pg_upgrade</a> module is required
|
|
for major upgrades. We also recommend reading the
|
|
<a href="/docs/current/upgrading.html">upgrading</a> section of the major
|
|
version you are planning to upgrade to.
|
|
</p>
|
|
|
|
<p>
|
|
Upgrading to a minor release does not normally require a dump and restore; you
|
|
can stop the database server, install the updated binaries, and restart the
|
|
server. For some releases, manual changes may be required to complete the
|
|
upgrade, so always read the release notes before upgrading.
|
|
</p>
|
|
|
|
<p>
|
|
While upgrading will always contain some level of risk, PostgreSQL minor releases
|
|
fix only frequently-encountered bugs, <a href="/support/security/">security</a>
|
|
issues, and data corruption problems to reduce the risk associated with
|
|
upgrading. For minor releases, <em>the community considers not upgrading to be
|
|
riskier than upgrading.</em>
