It's not really important --- the only difficulty with not having them
is the one you already hit, that REASSIGN OWNED misses things it should
do. If you're planning an update or dump-and-reload shortly, I wouldn't
worry about it. What's much more worrisome is the question of whether
the same kind of data loss happened anywhere else, and that isn't
something that the available info tells me anything about.

If you do want to go around and do retail ALTER OWNER commands, you
certainly could. I thought for a moment that changeDependencyOnOwner
would complain about the lack of a pre-existing pg_shdepend entry, but I
see it won't, so it should work fine.
