Hi!
I've noticed that NaN floating point values fetches from DB as zero values because of using Atof(). There is no possibility to check whether the value is NaN or not via such functions like IsNaN() or IsNull(). Also I have a question about fetching integers: why atoi() call is used in this code, and not ScanInt()?

void PostgreSQLConnection::GetColumn(int i, Ref f) const
{
    ...

    switch(info[i].type)
    {
        ...

        case INT_V:
            f.SetValue(atoi(s));
            break;

        ...
    }

    ...
}

Here is a patch in attachments. Could you check and comment it?
