What I did was to reinstall 7.4, which successfully restored the dump.

I don't think I actually need to preserve OIDs; I was using the -o
option out of habit, having been recommended to use it at some point.
In any case, that's not the point; I'm not looking for support or
workarounds, but simply to have the bug fixed. Whether or not I need
to preserve OIDs, the documented upgrade procedure for the case where
OIDs do need to preserved is not working, and that clearly is a bug in
either PostgreSQL itself or the documentation.
