It sounds like you didn't get all the tables. If you do a SELECT
relfilenode FROM pg_class WHERE relname='pg_inherits' on another 7.4
database (I don't have one handy), you'll see what the filename should
be so you can look for it.
If you haven't done many DDL changes since the last backup, you could
possibly restore an old copy and use that info to reconstruct
pg_inherits.
