PEAR DB_DataObjects - PostgreSQL view error

When I try to run createtables.php to create classes with:
 build_views = true
I get the following error msg

[db_error: message="DB Error: insufficient data supplied" code=-20
mode=return level=notice prefix="" info="SELECT viewname FROM pg_views
[nativecode=ERROR:  relation "view_column_usage" does not exist]"]

however select * from pg_views where viewname='view_column_usage'
does return a result.

I'm using PHP Version 4.3.2 + Apache/1.3.24 + PostgreSQL  8.0.0
beta-dev1 on windows XP sp2 (bleah)

Any hints?
