Thanks.  I've done a bit more looking and found a few more places that
we can improve and I've pushed the result.

It feels like it would be good if we had a way to detect a few of
these issues much earlier than we are currently.  There's been a long
series of commits fixing up this sort of thing.  If we had a tool to
parse the .c files and look for things like a function call to
appendPQExpBuffer() and appendStringInfo() with only 2 parameters (i.e
no va_arg arguments).

I'll hold off a few days before pushing the other patch.  Tom stamped
beta4 earlier, so I'll hold off until after the tag.
