1) Does the table name tabletorecover occur in more then one SCHEMA?

2) Do you want only the table data for tabletorecover?

Assuming 1 is one SCHEMA only and 2 is tabletorecover data only then 
maybe something like:

1) pg_restore --schema-only --table=tabletorecover -d recovery backup.backup

2) In psql ALTER TABLE tabletorecover DROP CONSTRAINT the FK references 
in tabletorecover.

3) pg_restore --data-only --table=tabletorecover -d recovery backup.backup
