help with interface PostGres to c++

Hello, I am jeremy.

I have a problem with PostGres which prevent me to go
on.
We developed a high-level of PostGres to interface it
with c++.
We had no problem to transfer and get back simples
types like text, double, int...
But we met a big problem with more complicated types
like:date, array (float8[])

Have someone already met such a problem ?

Please answer me to my mail-box:
jeremy(dot)ergisi(at)syseca(dot)thomson-csf(dot)com
or
j_ergisi(at)yahoo(dot)fr

Thanks, and happy new year
