Adjust the documentation's coverage of aggressive VACUUMs to make it clearer that aggressive vacuuming isn't always strictly necessary. It's possible for non-aggressive VACUUMs to advance relfrozenxid/relminmxid without fail, given the right workload conditions. While this has always been true, it matters more with recent and pending improvements to VACUUM. These improvements make non-aggressive vacuuming more likely to advance relfrozenxid/relminmxid in practice. While this is an unrelated improvement to the docs, formally speaking, it still doesn't seem worth backpatching. So don't backpatch. |
