As far as I understand, pgloader starts N threads or processes that open
up N individual connections to the server. In that case, moving then
text->binary conversion from the backend into the loader won't give any
additional performace I'd say.
The reason that I'd love some within-one-backend solution is that I'd
allow you to utilize more than one CPU for a restore within a *single*
transaction. This is something that a client-side solution won't be able
to deliver, unless major changes to the architecture of postgres happen
first...
