No. It is not bug. Where is in a documentation your example?
Instead this, in the documentation is next:
YYYY = year (4 or more digits)
^^^^^^^^^^^
Timestamp range is 4714 BC -- 1465001 AC.

The PostgreSQL hasn't directly limited year. The to_timestamp() stop
parse YYYY at first non-digit char.

Yes, it's right.
If you want store full timestamp into one big number is better year
keep to end of this number, like:
test=# select to_timestamp('08160000012000', 'MMDDHH24MISSYYYY');
to_timestamp
------------------------
2000-08-16 00:00:01+02
And YYY, YY, Y ... it's *hell*, and we support it because Oracle has it
too. How number you want create from:
'01' -- 'YY' ---> 2001, 1901 or 0001 .. grrrr
to_timestamp() use last possibility.
Some commets/suggestions about greater years than 9999 in
to_timestamp() / to_date()?
Thanks,
