Asterisk 1.0.9 packages require PostgreSQL 8.0 to build

[Jérôme Warnier]

I tried to "backport" version 1:1.0.9.dfsg-1 to Sarge, and it fails
because it expects PostgreSQL 8.0.
As even Unstable does not ship with 8.0, this is an important bug
(FTBS).

The problem is the following line in apps/app_sql_postgres.c:
#include "postgresql/8.0/libpq-fe.h"

Thanks
