When the timeout expires, the server sends the error message and

now recv() returns WSAECONNABORTED(10053) instead of WSAECONNRESET(10054).
On the other hand, I cannot reproduce this behavior with a remote server
even if pause psql just before the recv() call to let the RST win the race.
So I get:
postgres=# set idle_session_timeout = '1s';
recv() returned 15 errno 0
SET
recv() returned -1 errno 10035 (WSAEWOULDBLOCK)
postgres=# select 1;
recv() returned 116 errno 0
recv() returned 0 errno 0
recv() returned 0 errno 0
FATAL: terminating connection due to idle-session timeout
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
recv() signals EOF like on Unix.
Here I connected from a Windows virtual machine to the macOS host, but
the Wireshark dump looks the same (there is a RST) as for a localhost
connection.
Is this "error-eating" behavior of RST on Windows specific only to
localhost connections?
