Am I doing something wrong or should some history be cleared?

Reset the stats for that database. You can check the date of last reset with:

select stats_reset from pg_stat_database where datname = 'database_name';

and reset it with:

||pg_stat_reset()
||
||Reset all statistics counters for the current database to zero (requires superuser privileges by default, but EXECUTE for this function can be granted to others.)||
