Description:
I tried to install for the first time mediawiki, and I got the following message:

Mediawiki tried to access the database via wfGetDB(). This is not allowed.

Are you using Postgres? Mysql? Sqlite?

For other devs maybe looking at this: Looks like a change in ParserOptions causes this to load from the RequestContext user (which doesn't exist in the installer!). Although it's a similar bug, it's *not* the same as bug 28172 per the stack trace.

The server's php has postgres, mysql and sqlite capabilities. I tried disabling postgres module from PHP and got the same error. The database that I will use is mysql but the error appears just entering the URL for installattion, it didn't even show up the first step. I have read the bug 28172 and it's similar but not the same (seems to be some steps ahead).

What strange!.... I tried few minutes ago again without changing anything using the same URL and the installation worked!

Stumbled upon a similar error. Just cloned from github, Composer installed and run the installation. It crashes while creating the administrator account:
