Return null if there is no client certificate. This is how it has
always been documented, but in reality it returned an empty string.

Subject: [PATCH v4 4/4] Add more columns to pg_stat_ssl
Add columns client_serial and issuer_dn to pg_stat_ssl. These allow
uniquely identifying the client certificate.
Rename the existing column clientdn to client_dn, to make the naming
more consistent and easier to read.

Return null if there is no client certificate. This is how it has
always been documented, but in reality it returned an empty string.

Subject: [PATCH v4 4/4] Add more columns to pg_stat_ssl
Add columns client_serial and issuer_dn to pg_stat_ssl. These allow
uniquely identifying the client certificate.
Rename the existing column clientdn to client_dn, to make the naming
more consistent and easier to read.
