+1, but I think the description of that field in the pg-stat-archiver-view
table is also pretty misleading. Maybe like
- Name of the last WAL file successfully archived
+ Name of the WAL file most recently successfully archived
and similarly s/last/most recent/ for the other fields claiming
to be "last" something.
