I've seen something like this -- it was due to an embedded null (\0) in a
string value being inserted (presumably at the end of 'SCRAPBOOK', here)
which the JDBC driver doesn't escape and the backend appears to treat as
"end of query string". Took me a while to find as printing Strings doesn't
show nulls!

I experimented with escaping it in the driver, but it looks like the backend
doesn't support embedded nulls in TEXT either? (the stored value is silently
truncated at the null).
