HI Julien,
In my current database index size is very large compare than table (if table size is 30 GB and index size is 90GB) ,
thatwhy We running full vacuum monthly basis to increase the system performance and data reclaim .
Auto Vacuum is also configuration in system.
" maintenance_work_mem " paramater size to 2GB configure in system.
System configuration as below:
CPU - 42
RAM -70GB
Regards,
Ram Pratap.

The only thing that can be done to make it faster is to use a 1GB maintenance_work_mem.
But why do you need to do frequent database wide VACUUM FULL in the first place? Do you really have massive bloat on
everysingle table in the database?
Do you have adequate autovacuum configuration, or additional VACUUM jobs if that's not enough?
