Actually, I'd like to know this too :-)
I think that there is no difference really...
But what confuses me is - why are there two completely separate types?
Is it just to keep the standards happy?
Or is there some hidden difference in the behaviour?
For example, there used to be a 'datetime' in 7.2, that was just an
alias for timestamp without timezone -
so that:
create table times (t timestamp without time zone, d datetime);
\d times
Column | Type | Modifiers
--------+-----------------------------+-----------
t | timestamp without time zone |
d | timestamp without time zone |
But if I try the same thing with text and varchar, I get two different
type - text and character varying...
Could somebody who knows shed some light on this?
Thanks!
