The main reason is that I'm working on a Sqlite back-end for Darcs, that will be used to store file contents. I think to choose Takusen as back-end library mainly because it has the blob functions of Sqlite already mapped.
Umm, yes... I wrote the blob FFI imports for Sqlite, as I planned to prototype Takusen's blob support in Sqlite first, but never got any further with it. It is completely untested.
In Darcs PackedStrings are used to store file contents in memory. I don't think that it would be very efficient to store files of megabytes in a text column (there could be encoding problems too).
Also, in Sqlite 3.4, they introduced new functions for incremental reading / writing of Blobs. I could use them in the future.
Seems reasonable. I recall Oleg saying something privately a while ago about an API for large objects. He may have some ideas for this.
