This is actually a good question --- why does ssh do it that way and
Postgres does it another, more like a web server/client.  Maybe it is
because ssh allows the user to create one key pair, and use it for
several independent servers, while Postgres assumes the client will only
connect to multiple related servers controlled by the same CA.  With the
Postgres approach, you can change the client certificate with no changes
on the server, while with the ssh model, changing the client certificate
requires sending the public key to the ssh server to be added to
~/.ssh/authorized_keys.
