SV: SV: SV: SV: Problem with ssl and psql in Postgresql 13

Hi,


I did a final test before logging out for Christmas because i found a thread in hackers discussing some issue with GSS and SSL.

So if i set gssencmode=disable on my pgsql-13 to postgres 13 server connection i get an SSL connection.


Is this expected behaviour?


$ /usr/pgsql-13/bin/psql "dbname=postgres user=kalle host=server gssencmode=disable"
Password for user kalle:
psql (13.1)
SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off)
Type "help" for help.

Hi,


Yes it´s odd. I think we begin with download/reinstall and take it from there.

The server name is just letters and numbers so I think we can rule that out.


Christmas is coming up fast as usual so I think I will pick this up in January.

Thanks for all the help and Happy Christmas! Or God Jul as we say in Sweden.

That is just bizarre.  libpq should not ignore the sslmode=require option
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=require setting should
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.
