Well, I am sure whoever applied the patch, Tom, tested it:

    revision 1.85
    date: 2002/08/29 15:56:20;  author: tgl;  state: Exp;  lines: +15 -17
    Cause REINDEX to regard TOAST tables as regular relations, not system
    tables that need special defenses.  I believe this is okay even for
    TOAST tables that belong to system tables.

If you want to be sure, install 7.3 on a different port and test it.
