Quite a bit in pg_dump changed, but the relevant bit here is that we now
try to include in the pg_dump output any ACLs which have been changed
from their initdb-time settings for initdb-time objects. What that
means is that if you don't change the privileges for the public schema
from what they're set to at initdb-time, then we don't dump out any ACL
commands for the public schema. That ends up being incorrect in '-c'
mode because we drop the public schema in that mode and recreate it, in
which case we need to re-implement the ACLs which existed for the public
schema at initdb-time.
Thanks!
