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 ;
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.
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.

What user is the foldertest owner?
In psql l will tell you this.

Because the public schema is by default open to all:
https://www.postgresql.org/docs/9.6/static/ddl-schemas.html
"A user can also be allowed to create objects in someone else's
schema.
To allow that, the CREATE privilege on the schema needs to be
granted.
Note that by default, everyone has CREATE and USAGE privileges
on the
schema public. This allows all users that are able to connect to
a given
database to create objects in its public schema. ... "

In psql do dn+, that will show schema owners and who else has
privileges.
For what the different privileges are and how they are
represented in
the above output see:

Because the postgres user is a superuser and can do anything.

That is not the issue. pg_hba determines who can connect, what
you are
seeing is the Postgres privilege system determining what a user
can do
once they are connected. If it had been a pg_hba rejection you
would
have seen something like:
aklaver@tito:~> psql -d production -U guest -h localhost
psql: FATAL: no pg_hba.conf entry for host "::1", user "guest",
database "production", SSL on
FATAL: no pg_hba.conf entry for host "::1", user "guest", database
"production", SSL off
To get an overview of what users there are in your database
cluster in
psql do du
