[cl-rdbms-devel] is type management support extendable?

Hi,

I have just started to look at cl-rdbms and was wondering what the following means;

"Type management support (e.g. to help properly handle the NIL/false situation)"

Does this mean that I could define my own application specific column types and then when selecting/updating/inserting cl-rdbms takes care of converting to/from the db? So if I had some hairy struct that I wanted to save in a blob field I could define an appropriate column-type and related methods?
