I don't know the capabilities of partmen, but I would be surprised if it could automatically create foreign keys on the partitions.
Yes, the constraints on each of the child partitions and parent partitions were getting created automatically. As I see from information_schema.table_constraints, it shows one foreign key constraint in each of the child partitions created through the partman procedure.
It works smoothly without any issue, until we noticed this issue while trying to purge the partition from the parent table partition. But I believe this extension is extensively used , so I'm just wondering if I am missing something here with regards to foreign key creation using this automated partition creation/partman extension functionality.
