No, that message just regurgitates what you typed.  Magnus is
correct that the pattern will be case-folded if not quoted.
You can check with --echo-hidden (-E):

postgres=# \d public.some_idIds
/******** QUERY *********/
SELECT c.oid,
  n.nspname,
  c.relname
FROM pg_catalog.pg_class c
     LEFT JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
WHERE c.relname OPERATOR(pg_catalog.~) '^(some_idids)$' COLLATE pg_catalog.default
  AND n.nspname OPERATOR(pg_catalog.~) '^(public)$' COLLATE pg_catalog.default
ORDER BY 2, 3;
/************************/

Did not find any relation named "public.some_idIds".

So it is in fact looking for public.some_idids.
