I seem to get the incorrect behavior on my 7.4 beta 1 system. The
behavior on my machine is really wierd in fact even without times
involved:
test=# select to_timestamp('2003-06-04', 'YYYY-MM-DD HH24:MI:SS') ;
to_timestamp
------------------------
2003-06-04 00:00:00-07
(1 row)
test=# select to_timestamp('2003-06', 'YYYY-MM-DD HH24:MI:SS') ;
to_timestamp
------------------------
2003-06-04 00:00:00-07
(1 row)
test=# select to_timestamp('2003', 'YYYY-MM-DD HH24:MI:SS') ;
to_timestamp
------------------------
2003-01-01 00:04:00-08
(1 row)
test=# select to_timestamp('2003-06', 'YYYY-MM-DD HH24:MI:SS') ;
to_timestamp
------------------------
2003-06-04 00:00:00-07
(1 row)
test=# select to_timestamp('2003-07', 'YYYY-MM-DD HH24:MI:SS') ;
to_timestamp
------------------------
2003-07-04 00:00:00-07
(1 row)
