If I've to setup two databases in Render such that schema of one database is required in the other, then I would've to use foreign data wrappers, but they're not supported in Render.

Also, is it possible that all the DB features which are and are not supported by Render, can be mentioned in the docs? Because I had to spend several hours figuring out why foreign data wrappers won't function in Render's database, only to receive a mail from Render's support team clarifying that FDW isn't supported yet.
