the original request was to allow extra commas such as perl does
-- for example:
create table xyz (
f1 int4,
t1 text,
-- v1 varchar(25),
s1 serial, -- note extra trailing comma
);
select
v.fld1,
-- t.fld2,
v.fldN, -- extra comma
from
tbl1 t,
view1 v, -- extra comma
where
...
PLUSSES:
1 it's easier to cut & paste whole lines
2 it's easier to comment out any line
3 allows quicker munging of source code, saving precious
programmer time (big, Big, BIG plus, in the long run)
MINUSES:
1 requires some tweaks to postgres source code
2 nonstandard -- rubs philosophical purists the wrong way
3 increases iterations through code as extra commas are added
or removed (when lines of sql code are moved around), eating
up programmer time
IMHO:
let the purists code strict ISO if they like; we're not
recommending that the current paradigm be CHANGED to allow extra
commas, only that a new one be ADDED to allow extra commas.
regarding nonstandard -- we wouldn't ditch "create rule" or
"inherits" just because the standards folk haven't learned to
appreciate them yet, would we?
i've secretly wanted this feature for months and months, but i
didn't have the globs to ask for it. :)
can we vote? (no florida jokes, please...)

note:
in "CREATE TABLE" you can specify a primary key at the end of
your field defs, to accomplish just about the same effect:
create table thisway (
code char(6),
name varchar(20),
amt float8,
other int4, -- pseudo extra comma
PRIMARY KEY( code )
);
of course, this approach works only for table creation.
