Interchange

Hi List,
    Well i know its not apropriate to throw a question like is anyone is
working on
interchange in this list, who could be helpful to me. But its just a
question of coincidence that iam
looking at to find some queries that i hold to be answered.
Well iam totally new to PGSQL and Interchange. Well as of now i dont require
much info on
PGSQL , but for interchange.

Well interchange seems to be with endless options.

But from a database perspective i seem to be stuck with some unanswerable
situation
where i couldn't find relavant information for certain fields rather, i
couldn't find certain
tables itself.

Does anyone has a script for all the IC table structures ? or maybe even
better field level
info on each and everything.

I searched and found scripts for some 14 tables but i guess there goes a lot
than what iam
referring to.

Iam currently looking for tables structures for the admin's interface , i
presume there are some hidden tables,
does anyone know the structure of the same and maybe a brief description of
the same ?
And to move from the existing text file to a DB like pgsql is there any
script being provided by interchange
for the tables used etc ?
If so then can anyone specify where i can find them ?

Lookin for immense help from this list asap.

Thnx in advance.
Cheers,
Balaji
