PQdeleteTuple function in libpq

Hello.

I'm some kind of PQdeleteTuple function will be very usefull in libpq.
Because right now after deleting some record I need refetch result
set, or mark tuple as deleted and this is headache for me.

So I checked fe-exec.c sources and wrote this:

int PQdeleteTuple(PGresult *src, int tup_num)
{
if (!src)
return NULL;

int i,
field;

/* Invalid tup_num, must be < ntups */
if (tup_num < 0 || tup_num >= src->ntups)
return FALSE;

free(src->tuples[tup_num]);

for (i = tup_num; i < src->ntups - 1; i++)
{
src->tuples[i] = src->tuples[i + 1];
}
src->ntups--;
return TRUE;
}

But I'm pretty sure, that "free(src->tuples[tup_num])" is bullshit!
Because memory is allocated by pqResultAlloc, which in turn plays with
memory blocks and so on...

Can anyone help me in this?

PS I'm not a C guru, so don't please kick me hard. :)

Thanks.
