I agree. I would never expect to add quotes to a C string to preserve
case (outside SQL), and the fact that PQfname doesn't return the string
in quotes is another inconsistency. It is sort of like case coming out
is significant, but case going in has to be quoted --- am I getting this
right? Do we do this in other areas?
