Add :initform in generate-defclass if the DB column has DEFAULT

[rudolph-miller]

• [ ] add ALTER TABLE table_name ALTER column_name SET DEFAULT default_value;
• [ ] drop ALTER TABLE table_name ALTER column_name DROP DEFAULT;
• [ ] create table CREATE TABLE db_name.tbl_name (col_name1 data_type1 DEFAULT default_value, col_name2 data_type2, ...);

Is it really necessary though we have :initform of defclass to set the default value when make-instance?
