My cross-version upgrade testing tool just threw up this failure,
upgrading from 9.5 to head:
CREATE ROLE "dummy_seclabel_user1";
CREATE ROLE
ALTER ROLE "dummy_seclabel_user1" WITH NOSUPERUSER INHERIT
CREATEROLE NOCREATEDB LOGIN NOREPLICATION NOBYPASSRLS;
ALTER ROLE
SECURITY LABEL FOR "dummy" ON ROLE "dummy_seclabel_user1" IS
'classified';
psql:pg_upgrade_dump_globals.sql:25: ERROR: security label provider
"dummy" is not loaded
This error might not be terribly new - it's been masked by another
earlier problem that I have now catered for in the tool.
cheers
