ERROR: invalid input syntax for type timestamp with time zone

Hi All,

Consider the following test:

postgres=# select version();

version
------------------------------------------------------------
-----------------------------------------------------
PostgreSQL 9.3devel on x86_64-unknown-linux-gnu, compiled by gcc (GCC)
4.4.6 20120305 (Red Hat 4.4.6-4), 64-bit
(1 row)

postgres=# create table test ( a timestamptz);
CREATE TABLE
postgres=# insert into test values ( 'Sat Mar 11 23:58:48 1000 IST');
INSERT 0 1
postgres=# select * from test;
a
------------------------------
1000-03-12 03:52:16+05:53:28
(1 row)

postgres=# insert into test values ( 'Sat Mar 11 23:58:48 10000 IST');
ERROR: invalid input syntax for type timestamp with time zone: "Sat Mar 11
23:58:48 10000 IST"
LINE 1: insert into test values ( 'Sat Mar 11 23:58:48 10000 IST');

So, if you see while trying to insert date 'Sat Mar 11 23:58:48 *10000* IST'
, its returns with invalid input syntax. Error coming from the stack
(timestamptz_in() -> DecodeDateTime()).

But when I tried to enter same date with other format then it does work.

postgres=# insert into test values ( '*10000*-03-11 23:58:48');
INSERT 0 1
postgres=# select * from test;
a
-------------------------------
Sat Mar 11 23:58:48 *10000* IST
(1 row)

Looking at the code, it seems like for Postgres,MDY datestyle DecodeDateTime()
doesn't handle date properly if year is greater then 4 digits (greater then
9999). Do you see this as bug or expected output ?
