Consider: SELECT (NOW() - '1-Aug-2011')::text || ' ago.' user_string;
yields: "3 days 18:59:24.781174 ago."

Hi Amitabh,
Yes, I already took a glance of the Date/Time functions. But what
I’m expecting is something more meaningful/user-friendly value to be
returned than from the actual return value of these functions available here.
I’m just finding out whether this could be solved at query level itself.
For example, there is age(timestamp, timestamp) function.
If I call like this select
age(current_timestamp, (current_timestamp - interval '1 day')) it returns
“1 day”. But what I’m expecting to be returned
from the function is something more meaningful/user-friendly to the end users.
In this case, I wanted it to return “yesterday”, similarly today, 15
minutes ago, 1 week ago, etc.
Regards,
Gnanam

Have you looked into the date
time functions already ?

Hi,
Is there any built-in function/add-on module available in PostgreSQL, that
converts a given "timestamp"/"timestamptz" value into its
relative distance
from CURRENT_TIMESTAMP? For example, relative distance as today,
yesterday,
5 minutes ago, 1 week ago, etc.
