I wrote that pg_stat_ssl uses the *issuer* plus serial number to
identify a certificate. What your patch shows is the subject and the
serial number, which isn't the same thing. Let's get that sorted out
one way or the other.
Another point, your patch produces
LOG: connection received: host=localhost port=44120
LOG: client certificate verification failed at depth 1: ...
DETAIL: failed certificate had subject ...
LOG: could not accept SSL connection: certificate verify failed
I guess what we really would like is
LOG: connection received: host=localhost port=44120
LOG: could not accept SSL connection: certificate verify failed
DETAIL: client certificate verification failed at depth 1: ...
failed certificate had subject ...
But I suppose that would be very cumbersome to produce with the callback
structure provided by OpenSSL?
I'm not saying the proposed way is unacceptable, but maybe it's worth
being explicit about this tradeoff.
