It seems entirely unlikely that that will produce a byte-reversed float
value; what I think will happen is that the byte-reversed value of
integer 1 will be converted into a host-format float and stored into
loadavg.
AFAIK you can't really do this in C without a union. Take a look at
pq_sendfloat4 and pq_getmsgfloat4 in the backend for examples.
