Flying-
reading the source displays
http://doxygen.postgresql.org/postgres_8c-source.html

/* Trouble if it didn't eat the whole buffer */
if (!isNull && pbuf.cursor != pbuf.len)
ereport(ERROR,
(errcode(ERRCODE_INVALID_BINARY_REPRESENTATION),
errmsg("incorrect binary data format in bind
parameter %d",
paramno + 1)));

the test is
StringInfoData pbuf;

http://doxygen.postgresql.org/structStringInfoData.html#42669853a3faef1df41850bfd686cb24

pbuf.cursor (plain 32 bit int) != pbuf.len(64)

i think you found a bug....
