Database does not contain large objects.
pg_dump starts to throw error
ERROR: permission denied for large object 200936761
Did you do the pg_dump as a superuser?
No.
pg_dump needs to be invoked by non-superuser also. It backs up two schemas, public and firma74 .
-n public -n firma74
command line options are used.
You can query that to see what is there. I would not go about deleting until you find what the large objects are for.
select * from pg_largeobject
returns empty table.
Database has approx 50 schemas and many thousands of tables.
