Please look at a new anomaly introduced with that commit. The following
script:
createdb regression

echo "
CREATE USER u1;
ALTER DEFAULT PRIVILEGES FOR ROLE u1 REVOKE INSERT ON TABLES FROM u1;

CREATE USER u2;
ALTER DEFAULT PRIVILEGES FOR ROLE u2 REVOKE INSERT ON TABLES FROM u2;
" | psql regression

pg_dump regression

triggers:
pg_dump: pg_dump_sort.c:454: DOTypeNameCompare: Assertion `0' failed.

Reproduced on master and REL_13_STABLE.

Best  regards,
Alexander
