Hi !

Is there any way to get the time like the following example ?

'2003-05-11 15:21:21'

should return

'15:21:21'


Thanks !!

You can use the to_char function to convert timestamps to text with
control over the output format.

Cast it to time:

regression=# SELECT '2003-05-11 15:21:21'::time;
   time
----------
 15:21:21
