Manual:PostgreSQL/pt-br

The purpose of this page is to collect information and experiences about running MediaWiki on PostgreSQL.

MediaWiki supports PostgreSQL since 1.7. See Phabricator for a list of issues. MediaWiki requires PostgreSQL or later, and PG database support enabled in PHP.

Most of the common maintenance scripts work with PostgreSQL however some of the more obscure ones might have problems.
