I'm strongly in favour of this patch. I am currently in this situation:

1. Web db user runs as non-superuser, non-owner.
2. I have a table of a tens of thousands of rows that I must delete
entirely and rebuild every day at least (pg_trgm word list)
3. It just gets slow over time, even with autovac.
4. I can't vacuum it as i'm not the owner, and I cannot truncate it either.
5. Table has no triggers or FK's whatsoever.

So, stephen frost's suggestion would be fantastic.
