Make the pie dough: Combine flour, salt, and sugar in a bowl. Work in butter until mixture resembles coarse meal. Add cold water and knead until dough forms. Wrap in plastic and refrigerate for at least one hour.
Form the crust: Roll out dough and transfer to a pie plate. Trim and crimp edges. Refrigerate until ready to fill.
Heat oven to 400°F (205°C).
Make the filling: Combine pumpkin, sugar, salt, and spices in a saucepan. Cook over medium heat for 5-7 minutes. Whisk in cold cream and eggs. Pour into prepared crust.
Bake pie for 15 minutes, then reduce heat to 350°F (175°C) and bake for another 30-40 minutes until set.
Let pie cool completely.
Make pecan praline topping: Combine brown sugar, butter, cream, and salt in a saucepan. Simmer until thick. Stir in vanilla and pecans.
Serve pie in wedges, topped with pecan praline sauce.
