Summary: The TLS behavior of psql changed between 16.3 and 16.4 as shown 
below.

Have you tried the current release (16.6)?
			regards, tom lane


Yes, but psql 16.6 fails in the same way:

root@hetzner-2:~# docker run -it postgres:16.6 psql "host=headcrashing.eu port=5432 dbname=postgres user=postgres password=HeadcrashingPostgres2022 sslmode=require"
psql: error: connection to server at "headcrashing.eu" (49.13.53.107), port 5432 failed: SSL error: tlsv1 alert no application protocol
