Yes, this is certainly our error message:

pg_exec() query failed: pqReadData() -- read() failed: errno=0 No error

Of course, the "0 No error" is odd. I think that just means that read()
itself didn't set errno for the failure.

You are clearly base64 encoding the storage info, meaning it isn't some
strange character in the data. Are you using 7.2 for the server and the
client?

Yes. libpq.dll is version 7.2.1. So is the server.

My guess is that Win isn't handling some of the larger packets,
but I may be wrong. If it fails reliably, could you find the exact
length where it fails. That may help.

It is exactly 6106 bytes of raw data.
That is 8144 bytes of base64 encoded data.
Below this everything works just fine.

Could it be that Win32 somehow can't handle large tcp packets? Would
you create a TEXT field, and stuff 9k of a string into it and see if
that fails?
