Preheat the oven to 350 degrees F (175 degrees C). Grease and flour a 9x5 inch loaf pan.
In a large bowl, combine the flour, baking powder, baking soda, cinnamon, nutmeg, ginger, and salt. In a separate bowl, cream together the butter and sugar until light and fluffy. Beat in the eggs one at a time, then stir in the vanilla and pumpkin puree.
Carefully stir the wet ingredients into the dry. Mix until everything is just combined. Fold in the pecans, if desired. Pour the batter into the prepared loaf pan.
Bake for 55 to 65 minutes in the preheated oven, or until a knife inserted into the center of the loaf comes out clean.
