Correct, the most recent one that I could think of is pg_stat_checkpointer,
which pulled the checkpoint related columns from pg_stat_bgwriter.
In that case though, these are distinct background processes and
it's a clear distinction.

In this case, I am not so sure about this, particularly because
we will then have the autoanalyze and autovacuum fields in different
views, which could be more confusing to users than saying pg_stat_all_tables
has high level metrics about vacuum and analyze and for more details on
vacuum, refer to pg_stat_vacuum_tables ( or whatever name we settle on ).
