A new history file is created when a new timeline is opened,
which happens after point-in-time-recovery or promotion of
a physical standby server.
There must be something weird in the way you start PostgreSQL.
Examine the start script, maybe you can fix the problem.
These files are only necessary for point-in-time-recovery,
so you don't have to retain them any longer than you retain
your WAL archives.
