having read them back af

everything -- what is there now is very limited. And the mechanism for
contributing fixes for the official documentation, as Ivan says, does
make it rather difficult to contribute in a productive fashion. Way too
much overhead and distance between what

run it through a named pipe or socket straight to the network backup

Exactly. Live databases always have to be treated specially. You can use
