It can reason, but it can't understand. Why？

struct.error: unpack_from requires a buffer of at least 5 bytes for unpacking 5 bytes at offset 0 (actual buffer size is 0)

No file, test, or reproduction is provided. Start by reproducing the reported struct.error in the Redshift Python Connector and trace the empty buffer back to its source; done means the failure is explained and a regression test and fix prevent it.
