That is because the lines returned from pg_restore -l are not the full 
commands, they represent(generally) a summary of the object, its name 
and the owner.

The error message and your first example above show that the command is 
there. See at here:

https://www.postgresql.org/docs/current/app-pgrestore.html

in the Examples section how you can comment out the line. Then you could 
use -L to feed the list back to pg_restore.

Isn't fgrep -F redundant? As I understand it fgrep = grep -F
