This is why I'd VACUUM FULL in a planned manner, one or two tables at a time, and locally from crontab.

We did a "vacuum full" on a database which had been interrupted by a network outage.

 

We found the database size doubled afterwards.

 

Autovacuum also found a lot of orphaned tables afterwards.

 

The ophan temp objects went away after a cluster restart while the db size remained doubled.

 

Any idea?

 

Postgres 9.6.17
