 h4. Enabling Postgres trigram indexes
 
-  Feature "#15106":https://dev.arvados.org/issues/15106 improves the speed and functionality of full text search by introducing trigram indexes on text searchable database columns via a migration. Prior to updating, you must first install the postgresql-contrib package on your system and subsequently run the @CREATE EXTENSION pg_trgm@ SQL command on the arvados_production database as a postgres superuser.

Prior to updating, you must first install the postgresql-contrib package on your system and subsequently run the <code class="userprint">CREATE EXTENSION pg_trgm</code> SQL command on the arvados_production database as a postgres superuser.
+
+The "postgres-contrib package":https://www.postgresql.org/docs/10/contrib.html has been supported since PostgreSQL version 9.4. The version of the contrib package should match the version of your PostgreSQL installation. Using 9.5 as an example, the package can be installed and the extension enabled using the following:

+<strong>Centos 7</strong>
+<notextile>
+<pre><code>~$ <span class="userinput">sudo yum install -y postgresql95-contrib</span>
+~$ <span class="userinput">su - postgres -c "psql -d 'arvados_production' -c 'CREATE EXTENSION IF NOT EXISTS pg_trgm'"</span>

+</code></pre>
+</notextile>
+
+Subsequently, the <code class="userinput">psql -d 'arvados_production' -c '\dx'</code> command will display the installed extensions for the arvados_production database. This list should now contain @pg_trgm at .
