Hi,
IIUC, PostgreSQL does not support attaching a database to an existing
connection.
However I was told that I can use this:
https://www.postgresql.org/docs/9.3/postgres-fdw.html.

Is it the same thing? Why there is no simple

ATTACH <db> AS <dbname>


It is a different thing - postgresql_fdw does nested connect - it uses client-server protocol.

For postgres connect and sql engine process is one entity - and engine is written without a possibility to reconnect to another database.

Regards

Pavel
