I don't think so. If the PHP script makes an SSL connection to
PostgreSQL and PostgreSQL requests a client certificate, then the
PHP script will need access to a private key to respond correctly.
The HTTP client's private key won't be available to Apache/PHP (at
least not via the HTTP connection) so the script will need to use
a private key of its own. I'm not aware of a way for Apache to
proxy PostgreSQL's SSL negotiation with the PHP script back to the
HTTP client.

As far as I can tell no such matching is done. I can make SSL
connections to PostgreSQL as any user with the same certificate,
and I don't see anything in the documentation that allows that to
be configured. If I've overlooked something then somebody please
point it out.
