Defining the value as NAMEDATALEN-1 is reasonable (I was thinking of
suggesting that myself), but it seems like a recipe for confusion to
use name_data_len to refer to NAMEDATALEN-1.  Perhaps the GUC variable
name should be max_name_len or some such.

Also, should func_max_args and index_max_keys become max_func_args and
max_index_keys?

I'm not all that concerned about the names personally, but I want to
forestall any temptation for Bruce to start renaming these values later,
as he's felt free to do in the past ;-).  My expectation is that the
names of these GUC variables will get embedded into client-side code
fairly quickly, and so it will not do to fool around with the names
later.  We must decide what the naming convention is and then stick to
it.
