[Zope] WACK Book question/errata?

I'm trying to use the example (Chap 3, pgs.64-65) with a Postgres db. The gadfly example didn't work either. The problem seems to be with the forms. addNewRecordForm_html result_html I followed all examples to the letter. I can create tables, insert records etc w/ SQL statements for both Gadfly and Postgres. Is there something I'm missing? Eric Dunn
