That sounds good to me:

-[ RECORD 3 ]----------------------------------------------
name       | max_func_args
setting    | 32
-[ RECORD 4 ]----------------------------------------------
name       | max_index_keys
setting    | 32
-[ RECORD 5 ]----------------------------------------------
name       | max_name_len
setting    | 63

I'll finish up the docs and commit this tomorrow, barring strong 
complaints. It will require an initdb -- should I hold off for other 
pending changes also requiring initdb?
