Hi,
I've found this issue in the migration process from Oracle. There are many tables which partition by timestamp column (1 month) . But this column might contain oracle empty date (January 1, 4712 BC) that used for identify the partition as "do not drop".
In this case, when I insert new row with current date in the column the pg_pathman tries create all partitions between empty date and current date.
Does pg_pathman have a setting to disable the creation of empty partitions?
