I don't really want to change PQfname; that would probably break more
apps than changing PQfnumber.
We could achieve the property you suggest if we forgot about
case-insensitive matching and dequoting, and simply made PQfnumber check
for an exact match.
Or we could try some combination behavior (say, try exact match, then
if no luck apply the dequote/downcase logic). This might offer better
backwards compatibility, but the more complex the behavior, the more
potential for surprising corner cases ...
