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

Hi Magnus,

The clients 11 and 13 is on the same host.

Hmm, I get the same error if I set sslmode=require.

$ /usr/pgsql-13/bin/psql -d postgres --set=sslmode=require -Ukalle -hserver -W
Password:
psql: error: FATAL: no pg_hba.conf entry for host "nn.nnn.n.nnn", user "kalle", database "postgres", SSL off
FATAL: no pg_hba.conf entry for host "nn.nnn.n.nnn", user "kalle", database "postgres", SSL off

By default psql/libpq will fall back to a clear text connection if the
ssl encrypted one failed. Specify sslmode=require (or preferably
higher) in the connection string or set PGSSLMODE=require on the
client to disable that behavior. If you do that, my guess is you will
see a direct connection failure instead of that error?

PostgreSQL 13 did change the default value for minimum tls version to
1.2. But that seems unlikely to be the problem since you get TLS 1.3
when you use the old version...

I assume you're running both the 11 and the 13 client on the same host?
