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

MediaWiki obsługuje PostgreSQL od wersji 1.7. See Phabricator for a list of issues. MediaWiki requires PostgreSQL 8.3 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.

Czy PostgreSQL to dobry wybór dla MediaWiki?[edit]

Wikipedia uses MySQL so MediaWiki gets more testing on MySQL than PostgreSQL. While support for PostgreSQL is maintained by volunteers, most core functionality is working.

The MWDumperManual:MWDumper tool might help.

There is also a mediawiki_mysql2postgres.pl perl script in maintenance/postgres, but there is uncertainty whether it works.

Z PostgreSQL do MySQL[edit]

This is generally not recommended as converting from Postgres data types back to MySQL is not as simple an operation as the reverse.

There are however some scripts which may work.

Installation of MediaWiki with PostgreSQL and Nginx[edit]

The methods below briefly describe ways to install MediaWiki 1.25MediaWiki 1.25 with PostgreSQL 9.5.2 and Nginx 1.8 from their source on Ubuntu 14.04.

For cleaner and simpler maintenance, all the programs are installed in /home/s/src

cd /home/s
mkdir -p {src,bin,logs,daba,web}

## Install packages required by PostgreSQL 9.5.2

  opensp             \

## Install packages required by Nginx 1.8
sudo apt-get install \
  libpcre3           \
  libpcre3-dev       \
  zlib1g             \
  zlib1g-dev         \

## PHP could only use bison 2.7.1
wget http://launchpadlibrarian.net/140087283/libbison-dev_2.7.1.dfsg-1_amd64.deb
wget http://launchpadlibrarian.net/140087282/bison_2.7.1.dfsg-1_amd64.deb
sudo dpkg -i libbison-dev_2.7.1.dfsg-1_amd64.deb
sudo dpkg -i bison_2.7.1.dfsg-1_amd64.deb
rm -rf libbison-dev_2.7.1.dfsg-1_amd64.deb bison_2.7.1.dfsg-1_amd64.deb

# Prevent software update manager to overwrite these two packages
sudo apt-mark hold libbison-dev
