Обсуждение: advantages of multiple db's
Hi,
We have 1 db with everything in our entire enterprise in it (It’s a data warehouse). What are some of the disadvantages of using multiple db’s?
Can we join across db’s?

Postgres does not natively do cross joins, you can however use a third party tool called dblink
