There is some overhead with BLOBS: On the first call, the driver has
several queries to perform to set itself up. After that, accessing a blob
is a minimum of three fastpath calls (lo_open, lo_read, lo_close).
There isn't a way (yet) to store directly into a table. There was some
discussion a few weeks ago about this, and I have started to look at this,
but it wont be available until 6.4
