Unrelated, but you should definitely update to the latest minor version (so
14.5 right now).

Nothing here looks like a bug.  Note that your query is incorrect as there's a
dedicated "state" field to give this information since version 9.2, so a bit
more than 10 years ago.  You can refer to
https://www.postgresql.org/docs/14/monitoring-stats.html#MONITORING-PG-STAT-ACTIVITY-VIEW
for more details about this view.

I'm not sure if you had question related to the rest of the message, but if you
do please send a message to pgsql-general list instead
(https://www.postgresql.org/list/).
