Another layer of escaping for the escapes in the DB update script

Apologies for the previous patch that led to breakage; I "tested" in a
script in which I had already hardcoded the answer I wanted after
running into problems with the previous version of the script. Not
good testing practice.

Thanks to Bill Erickson for suggesting the extra escapes. Tested in
a clean environment this time, and it works.
