Look at what fe-protocol3.c:build_startup_packet() does with its options
argument (and see fe-connect.c:EnvironmentOptions to see what is passed
to it). Basically, libpq sets some connection parameters to values taken
from the environment (e.g. client_encoding from PGCLIENTENCODING). What
the documentation you quoted is saying is that the wire protocol doesn't
know or care where the values came from.
