vacuumdb did not analyze all tables?=

vacuumdb 15.3
database instance: 9.6.24

I manually analyzed 71 tables this morning at 10:42. (All those with
"rp20_y2021" in the relname.)

Three of the 71 tables were not analyzed. Why would that be?

(Five were not vacuumed, but I accept that some other process might have
blocked them.)

vacuumdb -U postgres -h $DbServer --analyze -j6 -t ... -t
cds.cdstransaction_rp20_y2021 -t ...

TAPb=# select schemaname||'.'||relname as table_name
, last_vacuum
, last_analyze
from pg_stat_user_tables
where schemaname||'.'||relname in ('cds.cdstransaction_rp20_y2021'
, 'css.image_annotation_rp20_y2021'
, 'tms.document_rp20_y2021')
order by 1;
