Powerdesign常见问题解决
一、通过调整以下两个参数，
菜单：Database=>Edit current DBMS
PGSQL73::Script\Objects\MaxConstLen
value=>255

PGSQL73::Script\Objects\Table\Maxlen
value=>255
可以避免在生成sql时的错误:

Reference constraint name maximum length is limited to 7 characters
Key constraint name maximum length is limited to 7 characters
Table code maximum length

二、取消检查
菜单：Database=>Generate database的Check model的勾去掉即可！
