Why have you skipped some of the rows posted for primary? E.g. the
sequential scans info?

Anyway, I think new data are not going to help us as the issue resolved
somehow, so the current data are unlikely to show the original cause.

You can either wait whether it happens again, or dig in the logs to see
if / why the autovacuum was not running on this table.
