Hi, 

I'm trying to copy a schema from one PG database (ver 11) to PG 10. 
Previously the first database version was 9.6 and the way I did the copying was 

ssh -o Compression=no user@host '/opt/pgsql/bin/pg_dump --no-tablespaces -n 
schemaname -Fc  -U dbadmin dbname'  | pg_restore -U dbadmin -h localhost -1 -d 
dbnme

However after migrating from PG 9.6 to 11, when I did the same thing as before, 
I started getting a bunch of commands in the dump like this

GRANT CONNECT ON DATABASE dbname TO usernameXX;

which don't work for me because the list of users is different between 
different machines. 
It is clear that the change is related to the way pg_dump is implemented now in 
PG11 that global objects are dumped. 
But the question is how do I duplicate the previous behaviour, i.e. Dump just 
the schema and permission on the schema, not on the database. 

I do know that I could grep the dump, but that's very annoying when dumping 
hundreds of millions of rows.

Thanks in advance for the help.
