Aha, the problem is not EXECUTE but QUOTE_IDENT:

  test=# SELECT quote_ident('public.test_j2');
     quote_ident    
  ------------------
   "public.test_j2"
  (1 row)

  test=# SELECT * FROM "public.test_j2";
  ERROR:  Relation "public.test_j2" does not exist

which is correct, because schema and relation names can contain periods.
To quote a schema-qualified relation name you need something like
"public"."test_j2" (or "public"."table.with_period_in_name") which
quote_indent can't handle because it doesn't know whether the
period is a schema / relation name divider or part of the relation name.

This has come up before, see:
http://archives.postgresql.org/pgsql-hackers/2002-11/msg00892.php

It would probably be easiest to leave out the quote_ident from your
function definition and do the quoting manually in the function call,
if necessary, which mostly isn't.
