The commands you are looking for are:

pg_restore -l to get the toc
pg_restore -L to use the toc

If you open the resulting file from something like pg_restore -l >
foo.toc it is just a plain text list of objects to restore.

I don't know how well it is documented but I am sure we would accept a
patch.

pg_restore allows you to do so. Something like:

pg_restore foo.sqlc --file=foo.sql

Large objects are stored in a central table called pg_largeobject, so
yes that would be accuarate.

You can't; that is a known and irritating limitation.
