How about creating an SQL statement that will make the change and
putting a blurb about it it in the README, INSTALL and/or FAQ?

This wouldn't require an initdb and would let people have the fix.

For things like this that update exising fields (vs adding/deleting
fields hard-wired for use in the backend), it should work, no?
