There is a thing called tablespace, which is basically, directory where files for db objects reside. You can specify it both when making new objects (https://www.postgresql.org/docs/current/sql-createtable.html, https://www.postgresql.org/docs/current/sql-createtable.html) and you can also move object between tablespaces ( (https://www.postgresql.org/docs/current/sql-altertable.html, https://www.postgresql.org/docs/current/sql-altertable.html). Just keep in mind that moving object means that it will get locked, data copied to new device, and then removed from old, and unlocked. > And will it help in case of losing connection to USB disk? (DB recoverable > instead of total crash)? Well, you need *all* data from all tablespaces to have fully working db. Best regards, depesz
