If you are sure that you have no use for the cumulative statistics gathered by PostgreSQL, you can just reset all table statistics by executing the following command:
SELECT pg_stat_reset();
This sets all statistics to zero, and you can detect table use by just looking for tables where any usage count is not zero.
Of course, you can make a backup copy of the statistics table first, as follows:
CREATE TABLE backup_stat_user_tables AS SELECT current_timestamp AS snaptime, * FROM pg_stat_user_tables;
