Yet another PostgreSQL C++ binding

Dear All,

I've written a C++ PostgreSQL interface library which I use in a couple
of open-source applications, and I thought that I would mention it here
in case it could be of use to anyone. Yes, I know there are already
several such libraries, but I believe mine has a unique feature:
queries are functors that use prepared statements. Here's an example:

Database db("dbname=foo, username=blah");
Query<string,int> insert_thing(db,"insert into things(name,num)
values ($1,$2)");
SingletonQuery<int, string> count_things(db,"select sum(num) from
things where name=$1");

Transaction t(db);
insert_thing("table",1);
insert_thing("chair",4);
int n = count_things("bed");
t.commit();

Note how the queries are declared using the $n placeholder syntax for
parameters. Once the queries are declared the fact that they are
queries can be almost forgotten - they can be used as functions.

I have written up some basic documentation here:

Do let me know if you find this useful.

Regards,

Phil.
