The big issue I see with this is that it would break PQfname on the
client end, since that's case sensetive too. Most client languages are,
so you really are between a rock and a hard place.

Making PQfname case-insensetive also screws up in Tom's example.

One way to appraoch this is to consider this a setting of the collation
of the name datatype. If a case-insensetive collation is selected at
initdb time, then Tom's example would indeed fail, but that's a choice
someone made. Problem being, you'd have to export that choice to
clients to make PQfname work, and that's going to messy.

Have a nice day,
