pg_restore: [archiver] entry ID -825110830 out of range -- perhaps a corrupt TOC

Greetings:

I already did some searches on the "pg_restore: [archiver] entry ID
-825110830 out of range -- perhaps a corrupt TOC" error and am still not
sure why my database's not restoring after upgrading the FreeBSD and select
ports such as PostGreSQL. I did see something from a long time ago about
altering the table, especially column names, quite possibly being a problem
and I have done a lot of that, but as many backups as I've also done this
past year, this' the first time I've had to use the restore again and am now
not even sure how to get my database back. If this seems familiar and
simple enough for anyone, please advise including which details may be
useful here.

Thanks,
