Firstly hypertable needs all PK contains partition column, in this case time, and in the other hand Django does not allow create multi column PK so you can’t create a PK that could contains the time column.

Second: if I have rows with repeated time, it will break unique constraints in time column.

How can you use Django and TimescaleDB together and make use of hypertables?

I have tried to create a table with time as primary key and eventually I have got duplicate key error inserting data in the table
