This makes me wonder: should libpq contain a function to do the opposite
too? eg.

string=GetValue(from a bytea type column)
PQunescapeBytea(string, some buffer, buffer's size)

- or is there already another way of doing it?

It seems to me that anyone using bytea with libpq will end up having
to reinvent this wheel. (Something worthy of being knocked up in my
Copious Free Time (tm))

Cheers,
