Обсуждение: pgsql: Allow type_func_name_keywords in even more places

Allow type_func_name_keywords in even more places

A while back, 2c92edad48796119c83d7dbe6c33425d1924626d allowed
type_func_name_keywords to be used in more places, including role
identifiers.  Unfortunately, that commit missed out on cases where
name_list was used for lists-of-roles, eg: for DROP ROLE.  This
resulted in the unfortunate situation that you could CREATE a role
with a type_func_name_keywords-allowed identifier, but not DROP it
(directly- ALTER could be used to rename it to something which
could be DROP'd).

This extends allowing type_func_name_keywords to places where role
lists can be used.

Back-patch to 9.0, as 2c92edad48796119c83d7dbe6c33425d1924626d was.
