Getting fancy errors when accessing information_schema on 10.5

Hi all,

here is an example:

SELECT    sequence_name AS relname, sequence_schema AS schemaname
    FROM information_schema.sequences
    WHERE sequence_schema NOT LIKE 'pg\_%' AND sequence_schema != ‚information_schema'': SQLSTATE[42809]: Wrong object
type:7 ERROR: "pg_statistic" is not a sequence 

This does not happen as SUPERUSER.
Is this a known bug?

Any help appreciated.
