v8- looks good to me.
Only one doc nit:
+ During a parallel vacuum, the leader and each of its workers reports its
+ own row, all sharing the same <structfield>relid</structfield>. Only
+ <structfield>phase</structfield>,
I think we should make it more clear about how long the worker rows exist
for. Maybe the below:
During parallel index vacuuming or cleanup, the leader and each active
worker report separate rows, all sharing the same
<structfield>relid</structfield>. Worker rows exist only while the worker is
performing parallel vacuum work.
