A vacuum full rebuilds the tables, so yeah if it didn’t successfully complete I would expect a lot of dead data.

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
