AFAIR there is no place in Postgres where performance of a pipe
connection is critical. Don't go out of your way to make it fast.

In fact, right offhand I only see two pipes used at all in the source
code: they are both in pgstat.c. It's fairly likely that that could be
redesigned if it poses a problem on Windows. (One of the pipes never
even transports any data; it's only used as a cheap-and-dirty means of
letting the statistics subprocess detect postmaster exit.)
