> I was discussing the design around incremental backup with Vladimir.
> Currently if WAL file is recorded in backup table, BackupLogCleaner would signal that the file can be cleaned up.
> However, cleaner chore doesn't notify BackupLogCleaner whether the file is actually deleted.
> This means that potentially large number of WAL file entries would stay in backup table.
> This issue is to investigate better cleanup strategy for the WAL entries.
