Tikvenik goes by a lot of names, but it is not a pie. It can be cut to resemble a pie and share a lot of ingredients with pumpkin pie, but they are different. For starters, Tikvenik is a Bulgarian Banitsa pastry, made using phyllo dough. Pies usually have a base crust or dough that is then filled and baked, while Tikvenik is rolled out and placed in a circular ring formation.
