to collect information and experiences about running MediaWiki on <a rel="nofollow" class="external text" href="https://www.postgresql.org/">PostgreSQL</a>. </p><p>MediaWiki supports PostgreSQL since 1.7, but please note that this is second-class support, and you may likely run into some bugs. The database most commonly used with MediaWiki is <a href="/wiki/Special:MyLanguage/Manual:MySQL" title="Special:MyLanguage/Manual:MySQL">MySQL</a><span style="display:none"><a href="/wiki/Manual:MySQL" title="Manual:MySQL"> </a></span>. See <a href="https://phabricator.wikimedia.org/tag/postgreSQL" class="extiw" title="phab:tag/postgreSQL">Phabricator</a> for a list of issues. MediaWiki requires PostgreSQL 10.0 or later, and PG database support enabled in PHP. </p><p>Most of the common maintenance scripts work with PostgreSQL; however, some of the more obscure ones might have problems. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Is_PostgreSQL_a_good_choice_for_MediaWiki?"><span id="Is_PostgreSQL_a_good_choice_for_MediaWiki.3F"></span>Is PostgreSQL a good choice for MediaWiki?</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Manual:PostgreSQL&action=edit&section=1" title="Edit section: Is PostgreSQL a good choice for MediaWiki?"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Wikimedia uses MariaDB so MediaWiki gets more testing on MariaDB than PostgreSQL.
