Is it?

Where is that in the docs. It does not appear in the page discussing
PQLIB and binary data transfers

Even the original sentence does not describe the problem we're seeing
here. It does not mention cross platform incompatibility.

Again, to me this sentence spells "you have a problem, we're not going
to help you out, deal with it". This is especially true if what Tom said
was true, that the text format does not maintain total precision. You
are essentially telling the user "you cannot move your data reliably
even between servers of the same version".
