I found following comment for using PostgreSQL with MediaWiki:
https://www.mediawiki.org/wiki/Compatibility#Database
"Anything other than MySQL or MariaDB is not recommended for
production use at this point."
This is a sad and disappointed statement for us. Should we help
MediaWiki community to enhance this?
Best regards,
