I'm not sure how that extra level of indirection gives you anything.
Haven't you just gone from "how do I configure my new SSLSocketFactory
instance without context?" to "how do I configure my new
SSLSocketFactoryFactory instance without context?" ?

If we want per-connection SSL configurability (not just per-JVM) then it
seems like we have to pass an actual instance to the driver at runtime.
URL parameters aren't going to do the job unless we also pass
factory-specific configuration info in the URL somehow, and that assumes
that you can actually represent that info in the URL (e.g. you have more
than just an object reference to your keystore..)

I also dislike having the driver do any classloading of client classes
itself. It causes havoc in a managed environment where the JDBC driver
may be loaded in its own classloader that does not have access to the
application classes. I added the new variant of PGConnection.addDataType
to solve exactly this problem; let's not reintroduce it elsewhere.
