  PostgreSQL query result area is removed and precision
  Add Date : 2018-11-21      
  Had been using PostgreSQL functions to piece together, today suddenly discovered they can be that simple, direct use of timestamp (0) to fix it up:

ls => select createtime :: timestamp (0) without time zone from users;
  2015-10-03 01:32:03
  2015-10-03 01:32:03
  2015-10-03 01:32:03
(3 rows)
ls => select createtime :: timestamp without time zone from users;
  2015-10-0301: 32: 03.080415
  2015-10-0301: 32: 03.080415
