>   I am working with freeradius and mikrotik gateway for a long time, but recently I detect in my PostgreSQL database, in radacct table some inconsistencies. First af all, I say that I have the standard configuration file (postgres.sql) for accounting queries.

If you are using default configuration you should have detail file logs
as well. That log is created for each NAS daily by default (NAS
IP/detail-date). Check the detail file to see if accounting Stop packet
was received while the session was still alive. Accounting Stop packet
should be the only thing that inserts dates there.
