<p>Creating PostgreSQL Upgrade</p> <p><b>New page</b></p><div>== Prerequisites ==<br /> <br /> dist-upgrade (or something similar) was executed and installed a new version of PostgreSQL side-by-side with the one from the previous operating system release. This articles assumes an upgrade from version 9.5 to 10 after an Ubuntu upgrade from version 16.04 to 18.04.<br /> <br /> == Upgrade ==<br /> <br /> &lt;code&gt;pg_lsclusters&lt;/code&gt; shows an online cluster for every version of PostgreSQL running on two different ports:<br /> <br /> Ver Cluster Port Status Owner Data directory Log file<br /> 9.5 main 5432 online postgres /var/lib/postgresql/9.5/main /var/log/postgresql/postgresql-9.5-main.log<br /> 10 main 5433 online postgres /var/lib/postgresql/10/main /var/log/postgresql/postgresql-10-main.log<br /> <br /> The SystemD service &quot;postgresql&quot; is responsible for both instances.<br /> <br /> pg_dropcluster 10 main --stop<br /> <br /> In the output of pg_lsclusters, the second entry would disappear now.<br /> <br /> systemctl stop postgresql<br /> pg_upgradecluster -m upgrade 9.5 main<br /> pg_dropcluster 9.5 main<br /> systemctl start postgresql<br /> <br /> Now, pg_lsclusters would only show the new instance running version 10:<br /> <br /> Ver Cluster Port Status Owner Data directory Log file<br /> 10 main 5432 online postgres /var/lib/postgresql/10/main /var/log/postgresql/postgresql-10-main.log<br /> <br /> == Cleaning up ==<br /> <br /> apt purge postgresql-client-9.5 postgresql-doc-9.5<br /> apt autoremove<br /> apt autoclean<br /> <br /> [[Category:Linux]]<br /> [[Category:PostgreSQL]]</div>
