I found myself the solution to the problem.
The trick is to check if the defaultValue() of the field is not null:
# Create new feature
new_feature = QgsFeature()
new_feature.initAttributes ( len ( layer.dataProvider().fieldNameMap() ) )
new_feature.setGeometry( ... )
# Populate fields with DEFAULT value in Postgres
new_attributes = layer.pendingFields()
for j in new_attributes:
fieldname = j.name()
fieldindex = layer.dataProvider().fieldNameIndex(fieldname)
fielddefault = layer.dataProvider().defaultValue(fieldindex)
if fieldindex == 0: # skip ogc_fid (mine is at index 0)
continue
if unicode (fielddefault) != "NULL":
new_feature.setAttribute (fieldindex, fielddefault)
# Populate your fields
new_feature.setAttribute ( ..., ... )
