... it could also be a type "sa_setup_role", and "_sa_setup_role"
is interpreted as the corresponding array type:

  CREATE DOMAIN sa_setup_role AS varchar;

  select _sa_setup_role('af_repo_app');
  ERROR:  malformed array literal: "af_repo_app"
  LINE 1: select _sa_setup_role('af_repo_app');
                                ^

Oh, of course --- that's a good deal more likely than my version.

Just coming back to this.  Don't know how to interpret this:

xxx_pub_dev_2_db=# select proname, pronamespace, oid from pg_proc where
proname like '%sa_setup%';
    proname     | pronamespace |   oid
----------------+--------------+---------
_sa_setup_role |      7038406 | 7869125
(1 row)

xxx_pub_dev_2_db=# drop FUNCTION if exists _sa_setup_role;
DROP FUNCTION
xxx_pub_dev_2_db=# select proname, pronamespace, oid from pg_proc where
proname like '%sa_setup%';
proname | pronamespace | oid
---------+--------------+-----
(0 rows)

xxx_pub_dev_2_db=# select _sa_setup_role('af_repo_app');
ERROR:  malformed array literal: "af_repo_app"
LINE 1: select _sa_setup_role('af_repo_app');
                              ^
DETAIL:  Array value must start with "{" or dimension information.
xxx_pub_dev_2_db=#

Puzzling.

I'd do:
pg_dump --schema-only xxx_pub_dev_2_db | grep -i -A5 _sa_setup_role

Note the -i.  That _might_ be important.

Do you have a custom type named sa_setup_role?

In psql do:

\dT

or

select * from pg_type where typname = 'sa_setup_role';
