Nothing leaps out to me from the script, but as you say, it's pretty
lengthy, so there's "a lot of there" there (to say it in the Clintonian
way :-)).

What I'd suggest first is that you seek to solve the "because the error
message, ddl file, and schema are lengthy" problem.

Try doing it in pieces; I'd try doing everything up to (but not
including) the alteration to segmentversions.

That means needing to lock the set multiple times, which is pretty evil,
but hopefully it does two things:

1.  It should get you to the point where *some* of the changes are
getting through, and

2.  It should allow narrowing the possible sources of the problem.
