Can someone please explain to me why these two give different results?
The idea is to get the number of seconds past 00:00:00, so the second
one is obviously correct.
foo=> select extract(epoch from current_time);
date_part
--------------
42023.026348
(1 row)
foo=> select extract(epoch from cast(current_time as time));
date_part
--------------
60030.824587
(1 row)
Isn't current_time already a time? Why is the cast necessary?
Thanks.
