Question about syntax check and back-sql

[ZhangPu <zhang@fjh.fujitsu.com>]

Hello,

Would you please give me suggestion about two questions below? 

Question 1:
Openldap front-end may does all syntax check on addition and modification 
operatings. I want to confirm is there exception that needs to check syntax 
by backend (like back-sql or etc.) itself on these two operatings.

Question 2:
It seemed like the current back-sql cannot support full functions which 
back-bdb has. But is there a detailed list for explaining the functions 
what are back-sql supported and what are not. 
Has somebody loaded all schemata into pgsql database successfully? 
If you have, do you mind show me your meta.sql as example? 

Thanks & regards
Pu Zhang
