A question I always have, and I didn´t find anybody answering it. If it´s possible
select * from MyDB.MySchema.MyTable;
And from user point of view ... all databases are accessible for the same postgres instance, user just says connect to this or that database, why is it not possible to do
select * from FirstDB.FirstSchema.FirstTable join SecondDB.SecondSchema. SecondTable;
Everything I found was how to connect, using FDW or DBLink, but not why.
