Обсуждение: Cross database joins feature request

Thanks for telling me that Postgres doesn't support cross-database joins.
I know MS Sql Server does. And one of the companies I worked for used it, to sometimes have a secure database with sensitive info behind a firewall join queries with a less secure database.

Is this something worth considering adding as a feature to Postgres?

No.  Most people who need this use schemas.  Frankly, if you can do
cross-db queries you are kind of losing the security value.

We do have /contrib/dblink that does cross-db queries.
