Unique id for postgres needs to be provided?

[borsemayur2]

I've previously worked with postgres and django-orm. The primary key id is auto-generated by django. The same thing happens with denodb and sqlite3. It is not the case with postgres. User has to provide an unique integer while creating a record. Can we have the same functionality as sqlite3 for postgres or is there any reason for not auto-generating the primary key for postgres?
