Argh, As soon as I sent it I realized even that's not right. The alignments of
our datums is specified by pg_type and doesn't vary by platform. There has
been some thought of making 8-byte data types like bigint pass-by-value on
64-bit machines in which case we would want to put that boolean flag in the
control file as well. But until that happens there's nothing to see here.
Sorry for the noise arguing with myself.
