Well what are those tags for?  They are not used by pg_restore, so they
are for users.  My understanding is that the tags help in editing a TOC
list for use by pg_restore.  What pg_restore actually reads are the
OIDs, but the tags are there so users can edit the files.  The tags can
also be used for ad hoc automatic processing.  They are not sufficiently
delimited and escaped for robustness in all cases, but it can be done if
you control the inputs and know what to expect.  But this is the same
problem before and after my patch.

Both of these cases are helped by my patch, and both of these cases were
pretty broken (for the object classes in question) before my patch.
