example column_defs_lowlevel bug

[wylsgame]

when column type is decimal(30,8) like:
SQL = """CREATE TABLE foo (
id decimal(30,8) primary key,
title varchar(200) not null,
description text);"""
result is :
NAME: id DEFINITION: decimal 30
NAME: 8 DEFINITION: primary key
NAME: title DEFINITION: varchar 200 not null
NAME: description DEFINITION: text
so how to fix this?
