Can't binary values can safely be sent cross-platform in DataRow
messages? At least from my ignorant, cursory look at printtup.c,
there's a binary format code path. float4send in utils/adt/float.c uses
pq_sendfloat4. I obviously haven't followed the entire rabbit trail,
but it seems like it happens.
IOW, why isn't there a cross-platform issue when sending binary data
from the backend to the client in query results? And if there isn't a
problem there, why can't binary data be sent from the client to the
backend?
