Hi,

It was discussed [1] here if C_F_I is needed in these
do_autovacuum/autovacuum_scores code paths, and it
was decided not to add them.

Also, at least on my tests with 100k evern with 1 million tables, I did
not see a reason to do so. These are catalog scans that should
happen quick enough, even in extreme cases, to not make
this worthwhile.

Others may have another opinion.
