Unresolvable unqualified warnings

[RekGRpth]

How can I resolve these warnings?

WITH s AS (
    SELECT "id" FROM public.task AS t LEFT JOIN "pg_catalog"."pg_locks" AS l ON "locktype" OPERATOR(pg_catalog.=) 'userlock' AND "mode" OPERATOR(pg_catalog.=) 'AccessExclusiveLock' AND "granted" AND "objsubid" OPERATOR(pg_catalog.=) 4 AND "database" OPERATOR(pg_catalog.=) 1 AND "classid" OPERATOR(pg_catalog.=) ("id" OPERATOR(pg_catalog.>>) 32) AND "objid" OPERATOR(pg_catalog.=) ("id" OPERATOR(pg_catalog.<<) 32 OPERATOR(pg_catalog.>>) 32)
    WHERE "state" IN ('TAKE', 'WORK') AND l.pid IS NULL FOR UPDATE OF t skip locked
) UPDATE public.task AS t SET "state" = 'PLAN', "start" = NULL, "stop" = NULL, "pid" = NULL FROM s WHERE t.id OPERATOR(pg_catalog.=) s.id RETURNING t.id;
PS001: Unqualified operator: '=' in state IN ('TAKE', 'WORK') at line 1
PS017: Unqualified object reference: t at line 1

You can fix the first issue by locking down your search_path like so: SET search_path TO pg_temp, pg_catalog;
Since the = is implicit there is no other way to explicitly specify the schema for the operator.
The 2nd seems to be a bug, since t is an alias and the actual table is fully schema-qualified it shouldnt complain here.
