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.
