Sorry. Most of the lists I send to have ReplyTo set, but a few do not.
And then I forget.

Right: I do see an error message when I try to insert a duplicate entry. It
happens to violate the (company_name, company_permno) uniqueness constraint.
2007-11-13 17:58:30 EST ERROR: duplicate key violates unique constraint
"company_name_x"
(I tried to insert a duplicate entry in the company_name field of relation
_company_. company_name_x is defined as:
"company_name_x" UNIQUE, btree (company_name, company_permno), tablespace
"stockd" )

Yes.

Yes, but I get those keys from a sequence only. I never enter them manually
or from a data file.
