Thanks.
See my previous response. Basically we need more information before this
can be solved.
I think I may have found the problem.
The role defined as:
CREATE ROLE "ronb" LOGIN
NOSUPERUSER INHERIT NOCREATEDB NOCREATEROLE NOREPLICATION;
GRANT users TO "ronb";
GRANT users2 TO "ronb";
users is a group role:
CREATE ROLE users
SUPERUSER INHERIT CREATEDB CREATEROLE NOREPLICATION;
users2 is a group role:
CREATE ROLE users2
NOSUPERUSER INHERIT NOCREATEDB NOCREATEROLE NOREPLICATION;
GRANT reports TO users2 ;
I think PostgreSQL doesn't know how to handle this conflicted commands.
What PostgreSQL does when such conflic appears? does it take the last
known command of grant?
Sadly, when there are more than one role it's impossible to know which
role was first. PostgreSQL shows them alphabeticly rather than by date
so in case of overlaping instructions its impossible to know which one
was first.

That may or may not be the problem. See:
https://www.postgresql.org/docs/9.6/static/sql-createrole.html
"The INHERIT attribute governs inheritance of grantable
privileges (that
is, access privileges for database objects and role
memberships). It
does not apply to the special role attributes set by CREATE ROLE
and
ALTER ROLE. For example, being a member of a role with CREATEDB
privilege does not immediately grant the ability to create
databases,
even if INHERIT is set; it would be necessary to become that
role via
SET ROLE before creating a database."
What you show above is part of the answer. The other parts are the
actual privileges on the objects. Also the command that created
the dump
file that you are trying to restore. Permissions/privileges
issues can
be complex and solving them requires a complete set of information.
