I got your point that now we need redundant typing for the objects
which already have reg* types, I think the advantage of this is we
don't need to have different functions names if we support multiple
object types like pg_get_table_ddl, pg_get_function_ddl,
pg_get_role_ddl, instead we can just do that with pg_get_ddl('table',
'mytable'); pg_get_ddl('function', 'mytable'); pg_get_ddl('role',
'myrole'); etc.
