The server and client can kick off a key renegotiation. Generally
it's left up to the client from what I can tell. The key specified
above is the public key used before the session is encrypted so that
makes sense to rekey... once encrypted though, I don't think it's
necessary to rekey that often. 10MB would likely be a nice and
conservative level that should be outside of the scope of most
PostgreSQL transactions. -sc
