Hi Mark,
Fetching a "real" type field from libpq doesn't look that intuitive.
So this example is super helpful. Thanks.

I am wondering whether we should provide PQgetfloatvalue() which does
what that example shows but transparently. It will return a float
value of the given field instead of char *. That will standardize the
way to fetch real typed values in libpq. That leads to the next
question. Do we need to introduce different PQget*value() for standard
C/SQL data types.
