Seafile on Postgresql

I see some old posts in regards to being a documented path to running Seafile on Postgres. Did this get dropped? is it another undocumented thing… I would be overjoyed if I could get rid if the Mysql/Mariah stuff and run it on my real database server. Is there known features in Mysql that wouldn’t work on Postgresql or just needs django connection and tables mapped?

Anyone know - save me some time would be appreciated for sure.

Kind Regards,

Postgres support was dropped in Seafile 7.1.
