Use 'MI' instead of 'MM' for the minutes. to_timestamp is quite lenient,
and interpretes the 00 in what you meant to be the minutes field as
month number. As there is no month 0, it uses January.
to_timestamp is much stricter in the upcoming 8.4 release, and will
throw an error for that query:
postgres=# select to_char(to_timestamp('2008-11-14 16:00:00','YYYY-MM-DD
HH24:MM:SS'),'day');
ERROR: conflicting values for "MM" field in formatting string
DETAIL: This value contradicts a previous setting for the same field type.
