For reading a single blob you need to get the field's characterstream, make
it a reader and then process it further.
(jdbc/query c ["select field from table" parameters]
:row-fn (fn [r] (some-> r
:fieldidentifier
.getCharacterStream
io/reader
(further processing
fns)))))
The some-> is needed because row-fn is done on all rows, and if the field
is null this would throw a NPE.

Niels
