Dangling large objects

I'm in a bit of a bind here. I wrote some code in our abstraction
layer to automatically unlink large objects when the row referencing
them is deleted (I know that they are only referenced once). However,
I neglected to include them in a transaction, so I'm pretty sure that
those unlinks never happened.

Is there any simple way for me to get a list of all large objects
in a database, so I can see if there are actually rows referring to them
and delete the ones that were not unlinked earlier?
