This seems like nonsense to me.  The initdb documentation says perfectly
clearly that the initial superuser's name is set by -U.  It does not
say anything about PGUSER.  I think the reference to libpq in the docs
probably should be taken out, because initdb never uses libpq to make
a connection, so libpq's defaults are not relevant.
