This patch adds a case that #63103 missed. When we have something like `ARRAY['a'::typ, 'b'::typ]`, we format it to `ARRAY['a'::typ, 'b'::typ]:::public.typ[]`. This causes issues if used in an `IndirectionExpr`, such as `ARRAY['a'::typ, 'b'::typ]:::public.typ[][1]`, as the `[1]` is interpreted as part of the type. This would result in errors when trying to use these expressions in default expressions. This patch checks for this specific case, and instead formats it as `(ARRAY['a'::typ, 'b'::typ]:::public.typ[])[1]`. Release note: None

When we have something like
ARRAY['a'::typ, 'b'::typ],we format it to
ARRAY['a'::typ, 'b'::typ]:::public.typ[].This causes issues if used in an
IndirectionExpr, such asARRAY['a'::typ, 'b'::typ]:::public.typ[][1], as the[1]is interpreted as part of the type.
This would result in errors when trying to use these
expressions in default expressions.
This patch checks for this specific case, and instead
formats it as
(ARRAY['a'::typ, 'b'::typ]:::public.typ[])[1].Release note: None
