quoting bug?
Given the following trivial trigger example:
-- create language plpgsql;
create table foo (a integer, b text, c timestamp);
create function foo_insert() returns trigger as $$
begin
raise notice '%', new;
return null;
end;
$$ language plpgsql;
create trigger foo_ins before insert on foo
for each row execute procedure foo_insert();
insert into foo values (1, 'two', current_timestamp);
I am surprised to see
NOTICE: (1,two,"Sat 09 Feb 16:47:44.514503 2008")
INSERT 0 0
I would have expected
NOTICE: (1,'two','Sat 09 Feb 16:47:44.514503 2008')
INSERT 0 0
i.e., a row whose columns look as though they went through quote_literal
rather than through quote_ident.
This is with yesterday's 8.3.0 (Feb 8 17:24 GMT)
Thoughts?
Cheers,
Patrick

I think what you're seeing is the syntax for row literals.
You can get an idea of how it looks without having to write trigger
functions, e.g.:
select row(1, 'second value', current_timestamp);
row
-----------------------------------
(1,"second value","2008-02-10 04:00:54.458647+11")
(1 row)
Note that anything which includes spaces, commas or brackets is double-quoted.
You can see it working the other way around by constructing a record
using the literal syntax.
=> create type foo as (a text, b int);
CREATE TYPE
=> select '("one", 2)'::foo;
foo
---------
(one,2)
(1 row)

This is the expected formatting for a composite type. Read

Thank you - sorry for noise.
