I found in a post from Jeff MacDonald the following example: bignose=> \d foo Table "foo" Attribute | Type | Modifier -----------+-----------+---------- start | timestamp | stop | timestamp | bignose=> select start,stop, stop-start as start_stop from foo; start | stop | start_stop ------------------------+------------------------+------------ 2000-06-22 20:37:12-03 | 2000-06-22 20:37:12-03 | 00:000 2000-06-22 20:40:40-03 | 2000-06-23 20:40:40-03 | 1 00:00 2000-06-22 20:40:53-03 | 2000-09-30 20:40:53-03 | 100 00:00 2000-06-22 20:41:08-03 | 2000-06-23 02:41:08-03 | 06:00 2000-06-22 20:41:30-03 | 2010-11-22 19:41:30-04 | 3805 00:00 (5 rows) Is it possible to get the start_stop field in hours ? And not in days, hours ? ex: 1 00:00 -> 24:00 In postgres what is the difference between the type datetime and timestamp? Thanks in advance Alex
