> If I use some other extension like timescale is that compatible with gel [...] Postgres is so powerful partly because of its ecosystem, so I want to know how much of that ecosystem is still useable if I’m using gel on top of Postgres

Playing nice with the ecosystem is the goal. We started off with more of a walled garden, but with 6.0 a lot of those walls came down with direct SQL support and support for standalone extensions [1]. There is a blog post coming about this specifically tomorrow (I think).

Replication/failover works out of the box.

Working on it.

Gel is built around its schema, so you will need to import your SQL schema. After that you can query things with EdgeQL (or SQL/ORM as before).

Yes, with access policy rules. E.g

   global hide_deleted: bool;

   type SoftDeletable {
     deleted: bool;

     access policy hide_deleted
       allow all
       when (global hide_deleted)
       using (not .deleted);
   }
