I have spent sometime to investigate the issue, it is reproduciable. In case of Windows, when pqsecure_raw_read() function error code WSAEWOULDBLOCK (EWOULDBLOCK) when no data queued to be read from the non blocking socket there is a need to log retry flag. Related error code can be retrieved via Windows WSAGetLastError() instead of errno, preprocessor SOCK_ERRNO handle it gracefully. PFA patch, it resolve the issue i.e.
