One of our customer is getting the below warning's and log statements in the postgres logs, the postgres version is 12.2. Because of which the log size is increasing quickly.
Is there any solution/workaround for this ? We have tried to turn off the "track_activities" settings in postgres.conf file but it is not helping.
Could you please also let us know, in what circumstances the stat collector will run ? So that we can do that activity to reproduce the issue in our setup.
LOG: could not rename temporary statistics file "pg_stat_tmp/db_0.tmp" to "pg_stat_tmp/db_0.stat": No such file or directory
