At least on other servers/drivers I believe nulls are supported (and
should be according to some spec) (The only special-meaning char is
single quote).

I'm wondering how the binary protocol works insofar as handling the NULL
byte; does it precede it with a backslash? I'm wondering if this would
be possible for the String conversion as well -- just for sake of
consistency with other DBs (and since some API inevitable expect users
to send binary data through a char-sequence interface)
