Ok. Grep shows that these 2 field types are rarely used - in fact only once each.

• civicrm_file has a blob column to hold file contents. But is this actually used? blob has a size limit of 64k, and AFAIK all files are stored as, well, files. I note that the column is very old (circa 1.5).
• civicrm_case_type has a mediumblob field to store the serialized definition. Since it's a serialized field, the type as far as the api is concerned should be Array. However, the serialization isn't declared in the schema (and there isn't a serialization type XML).

Yeh so I'm not sure but at the same time, I had a custom extension that I am writing where a table currently uses a MediumBlob field and this broke it, I suppose I could convert the column but it feels like if the DAO is outputting it as a legit type shouldn't the API be supporting it?

Ok let's merge this and continue the conversation.
