Hm ... not its index? If the table itself is gone, it's surprising
that you can get through session startup.

I had in mind just reindexing the specific table you're having trouble
with ... but this:
> ERROR: could not open file "base/11919/11680": No such file or directory
shows that there's another table that also has a problem, and there
may be more :-(. I don't know what the odds are that you can get out
of this completely. I would NOT recommend "reindex system" as a
blunderbuss solution. You do not know how much is corrupted and there's
a significant chance of making things worse by tromping over the whole
database using catalogs of uncertain reliability.
Did you identify which table 11680 is?
In the case of pg_db_role_setting, a possible solution is to "touch" the
missing file so it exists; it'll be empty, which means that you'll have
lost any ALTER DATABASE/ROLE SET settings, but that's better than not
being able to dump at all. (You might then need to REINDEX
pg_db_role_setting to get its indexes in sync with it being empty.)
Whether an equally drastic answer is tolerable for your other missing
table(s) depends on what they are...
