If I have a select statement where I am formatting both a duration ( interval
data type ) and timestamp ( timestamp with tz datatype ) I am getting an odd
behavior.
Note the extra characters following the seconds in the last_update column.
ace_db=# select port_id,
to_char(ppa.term_duration, 'HH24:MI:SS') as term_duration,
to_char(ppa.last_update, 'YYYY-MM-DD HH:24:MI:SS' ) as last_update
from log.peg_port_accumulator ppa;
port_id | term_duration | last_update
---------+---------------+------------------------
1 | 23:52:29 | 2014-10-17 11:24:44:58
11 | 00:00:00 | 2014-10-20 09:24:15:27
9 | 00:00:00 | 2014-10-20 09:24:16:53
6 | 01:41:19 | 2014-10-14 01:24:50:46
4 | 00:01:30 | 2014-10-14 01:24:52:11
2 | 00:00:05 | 2014-10-15 09:24:32:38
(6 rows)
If I change the last_update format to 'YYYY-MM-DD HH:24:MI' I will get the
desired result ( incorrectly ) including the seconds ???
psql -V
psql (PostgreSQL) 9.3.5
If I only select/format either the term_duration or last_update I get the
proper results with a format string.
ace_db=# \dS+ log.peg_port_accumulator
Table "log.peg_port_accumulator"
Column | Type | Modifiers |
Storage | Stats target | Description
---------------+--------------------------+------------------------------+---------+--------------+-------------
port_id | integer | not null | plain

orig_count | integer | default 0 | plain

orig_duration | interval | default '00:00:00'::interval | plain

term_count | integer | default 0 | plain

term_duration | interval | default '00:00:00'::interval | plain

last_update | timestamp with time zone | default now() | plain

Indexes:
"peg_port_accumulator_pkey" PRIMARY KEY, btree (port_id)
Has OIDs: no
Seems like a bug ?
