You are right. It is already know bug (feature:-) in 7.0.x, in this
version, to_timestamp() expect that year not must be exactly
4-digits but can be greater. A solution is use some separator like
'YYYY-MMDDHHMISS' or use YYYY as last in format template (as in your
first example).

In 7.1 is better analyse that fix it:

test=# SELECT version();
version
------------------------------------------------------------------
PostgreSQL 7.1devel on i686-pc-linux-gnu, compiled by GCC 2.95.2
(1 row)

test=# SELECT to_timestamp('20000512144548', 'YYYYMMDDHHMISS');
to_timestamp
------------------------
2000-05-12 14:45:48+02
(1 row)
