Hi Brock,

I haven't looked at all the code yet, but I like the interface and what
I've seen so far - I'm definitely interested in this library,

I have an implementation of your database library for MySQL. It's on my
hard drive at home and I'm broadband-less right now so if anyone wants
to see it let me know and I'll dial up tonight. It was very easy to
adapt to use the MySQL API.

I tested it with GCC 3.4 and 4.1 with no real problems.

postgresql/connect.cpp accidentally uses the <:: trigraph in the
typedefs at the top of the file. You need a space before the template
args to avoid that.

How do you handle NULL values? the postgresql::row_set_imp::get() function
doesn't seem to account for NULL, which would crash strlen(), atof() etc.
