on a somewhat related note, i'm working on extending/reworking the
binding mechanism so that users can add methods for lisp types that
serialize lisp values directly into the socket stream.

for that i've added a serialize-for-postgres generic (that by default
calls to-sql-string), but i need to spend more time to think through
how this could be integrated better (e.g. i'd like to support
serializers without an intermediate byte vector buffer). but i'm not
happy with the current code yet... although inserting
local-time:timestamp's without turning them into strings works
already.
