That is just bizarre.  libpq should not ignore the sslmode=3Drequire optio=
n
like that, unless it thinks it's making a Unix-socket connection, which
it should not think given the host specification.  (There's not a slash
in your server's real name, is there?  But if there was, v11 should
misbehave too.)

It seems like there must be some environment setting, or maybe a service
file, changing the behavior from what it should be on its face.  But
that theory has big flaws too: an explicit sslmode=3Drequire setting shoul=
d
not be overridable from environment, and even if it was, why wouldn't v11
act the same?

The only other conclusion I can think of is that your copy of libpq.so
is broken.  Maybe you should try redownloading/reinstalling v13.
