There is no default case here, setting the tableoid to InvalidOid is done when the archive doesn't support this particular feature. If we can't read the tableoid here, it's a corrupt TOC and we should abort.
Well, the v2 aborts.

Yes, which is better than silently propage the error.
Ok, silently propagating the error is bad, but crashing is a signal of poor tool.

That would demote what is today a crash to a warning on a corrupt TOC entry, which I think is the wrong way to go. Question is, can this fail in a non-synthetic case on output which was successfully generated by pg_dump? I'm not saying we should ignore errors, but I have a feeling that any input fed that triggers this will be broken enough to cause fireworks elsewhere too, and this being a chase towards low returns apart from complicating the code.
For me the code stays more simple and maintainable.
