Re: PostgreSQL Bug with simple function unexpectedly treating varchar parameter as an array

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=#
