Sorry for the delayed response. I've imported your patch and made a
small tweak, so that a simple database upload example works in all 3
supported DBMSes. The new code is pushed to the public Ur/Web Mercurial
repo.

Hi. I've faced 'non-printable character' error while trying to insert
a blob into the database. The error was mentioned in [1], but that was
all about strings, not blobs. Quick investigation shows that Ur
supports either E-string or plain syntax, and E-string is disabled for
the SQLite case (in sqlite.sml) . Fortunately, I've found the third
way - X-strings (X stands for hex) [2]. Simple hacky patch (attached)
illustrates the idea. Is it sqlite specific syntax extension? can we
use this approach for other databases?
