Hi Florian,

I have also noticed the bug, but I could not reliably reproduce it to
test a fix.  Could you please try if stunnel 5.18b5 works for you?
https://www.stunnel.org/downloads.html

protocol=pgsql does not seem to be a problem.  Otherwise, stunnel
would not be able to negotiate TLS.

Best regards,
	Michal Trojnara
