Hi
> An autovacuum can't be just aggressive; it's either anti-wraparound or normal.
But autovacuum _can_ be aggressive and not anti-wraparound.
I build current master and can see 3 different line types:
2018-09-24 23:47:31.500 MSK 27939 @ from [vxid:4/272032 txid:0] [] LOG: automatic aggressive vacuum of table "postgres.public.foo": index scans: 0
2018-09-24 23:49:27.892 MSK 28333 @ from [vxid:4/284297 txid:0] [] LOG: automatic aggressive vacuum to prevent wraparound of table "postgres.public.foo": index scans: 0
2018-09-24 23:49:29.093 MSK 28337 @ from [vxid:4/284412 txid:0] [] LOG: automatic vacuum of table "postgres.public.foo": index scans: 0
