To clarify, this is an issue that happens at install time when using the MediaWiki web installer with PerconaDB. This issue persists and is made evident with the use of SMW when the failure to install is worked around by using the MediaWiki command-line installer. I believe the core challenge, however, is still with PerconaDB integration with MediaWiki itself.

Thanks for the feedback, @MarkAHershberger just created the new bug: https://phabricator.wikimedia.org/T252481

@Ladsgroup were you able to set this up using Percona from the web installer? I was able to do it through cli (with the --dbtype percona flag), but later ran into similar issues when trying to update the tables after installing the Semantic MediaWiki extension: https://github.com/SemanticMediaWiki/SemanticMediaWiki/issues/4724

Good point, @Aklapper
Thank you for the suggestion; will move this over to a forum.

This is great! Thanks for the suggestion, @Anomie!

Hi, @Aklapper, thanks for the reply and hope you're staying healthy! I am currently using MediaWiki 1.34.0. From what I found in other forums, there seemed to be folks who saw this in older versions (<=1.31).
