Thanks, Tom, that's helpful! So, are you saying the the psql
client does all the buffering and not the server? Is the
buffering mandatory when using the libpq API? When you say
"most frontend client side libraries" do you know of any
exceptions who don't do that? Is the odbc client doing this
too?
I can see myself fixing this problem, but would like to know
if there is something else already?
thanks for the info,
-Gunther
