Thread:Project:Support desk/How can I use mwdumper with Postgresql command line/reply

Honest answer? Don't do it.

Sure, you can use Postgres, but if you do, that means that you will have to deal with brokenness and bugs. MediaWiki's Postgres support is by far not as mature as its MySQL support. Instead of trying to make things work with Postgres somehow, you should better set up MySQL and use that.

With MySQL you'll be far better off.
