I didn't mean "support" so much as "requires". My apologies for not expressing my thought more clearly.

AFAIK, the authentication is per-database, which means it has to read the database name from the client before authenticating, even if you are using certificates.
The bug in question involved the client sending an invalid database name.
Oops.

IIRC correctly my SSL/TLS, the authentication (and the start of encrypting the whole session) comes before anything else. I suppose when the client asks for connection to a database, he is already autheticated via his cert (and the dbms can check if he can effectively connect to *that* particular db).

SSL/TLS authentication has a very high overhead. Postgresql supports SSL/TLS authentication, but it also supports many other types of authentication so that you can choose what one is the best fit for your needs.
