Inheritance pg_largeobject table

Categorization: Unclassified
We are running PG11.11, and have more than 50T LO data about load into the pg_largeobject table. But 32T is the limitation.
We have created couple child tables that using inheritance to pg_largeobject, and we have tried use triggers(insert or update) to put into child tables. It doesn't work by use LO functions, ex lo_put, lo_create...seems never got triggered. But works with insert statement into the pg_largeobject.
If we move LO data from root table to child, lo_get will break.

Any ideas?

Is there a way store them into pg_largeobject? expand this table? Or we have to consider toast tables.

Thanks,
