Yes, vacuum full did the trick!

The bloating was primarily caused by the TOAST tables (several gigs
surplus), but the TOAST indexes are also slowly bloating as we have
indexes on a UNIX timestamp column. I will have to choose between
reindexing and upgrading...
For now I will keep an eye on the TOAST tables to see if the new FSM
value (1,000,000) keeps the TOAST tables at a reasonable size.
Thank you for the input!
Cheers,
Thomas.
