Mine is part of a general type converter that I have (cook()/uncook())
that handles all types I need to serialize.  psycopg might make the 
implementation of my cook/uncook functions slightly more concise, but
right now they are independent of the specific dbapi that I use, so I
might want to keep it that way (more componentized ;).
