C++ with PG 7.4?

Hi,

I see that version 7.4 introduces new features in the client
API area -- error codes, for instance.

So, I'm wondering if this will affect the way libpq++ works;
assuming that the SQL's don't use any feature that has changed
with version 7.4, should I expect any difference in code that
uses straightforward things like the following:

PgDatabase db ("host=blah.blah.com user=me dbname=db password=me");

if (db.ConnectionBad()) { .... }

if (db.Exec ("select .... from ....") != PGRES_TUPLES_OK)
{
for (int i = .... db.Tuples() ....)
{
.... db.GetValue (i, "field_name") .... ;
}
}

if (db.Exec ("insert into ..... ") != PGRES_COMMAND_OK)
{
....
}

I'm guessing that I would be able to use new features and
new error codes, but if I keep my programs the same (with the
old set of defined constants, etc.), they will work the same?
(again, assuming that the SQL's don't use any feature for
which the behaviour of the backend has changed with ver 7.4)

Also, are there any plans to re-include C++ client API as
part of the postgresql package? I don't mean to sound
ungrateful for everything that PostgreSQL offers, but I do
believe that removing C++ from the default distribution
was a great disservice to the community -- partly because
libpq++ does not even compile without some fine tuning
(well, programs written with it don't compile -- at least
on RedHat).

According to a survey you did a while ago, C++ had 2 or
3 times more users than C (off the top of my head -- I
couldn't access the "survey results" page, to check those
numbers).

I must admit to some personal bias in favor of C++, but
still, it's not like C++ is some obscure useless niche
language that only a few weirdos have heard of.

Thoughts, comments?

Thanks,

Carlos
