Current database takes almost all of SSD free space ~802GB. 800 GB of memory is taken by single table and it was never vacuumed since 2019. Recently i deleted old rows from the table and now i need to run VACUUM FULL to reclaim disk space back to OS. The problem is that there is no space left on SSD. I can connect external SSD (840 GB) but i don't know how to run VACUUM FULL and make it use external disk space.
