How can I calculate the number of second in some interval? Neither
the secods part, nor the seconds after midnight... Just the full
quantity of the seconds. I haven't find any function.

Oh, I'm sorry. This is extract(epoch from interval).

I think you can do that using
EXTRACT(epoch FROM interval-value)

SELECT extract(epoch FROM n);

How do I convert a length of time, measured in seconds, into a "point in

I have the need to output intervals (ages in this case).
PostgreSQL takes great care to handle months correctly (eg
take into account varying months lengths). This is only
possible if either end point or start point of an interval are
known. For post processing some of the ambiguity of what
"2 mons" means would be removed if "61 days" was returned.
Is there a way to tell PostgreSQL to return that type of
interval (eg use weeks, days,...

Recently there has been some discussion about attaching a timezone to
a timestamp and some other discussion about including a 'day' part
in the interval type. These two features impact each other, since
if you add a 'day' to a timestamp the result can depend on what timezone
the timestamp is supposed to be in. It probably makes more sense to use
a timezone associated with the timestamp than say the timezone GUC or the
fixed timezone UTC.

Hi all
How can I access partial seconds on the system clock?
I measure air speed and water flow in a heat-exchanger test stand and
count pulses from both water meter and air speed meter. I divide the
amount of these counts over a certain interval with the time of that
interval. Since I only have seconds, I need to wait 100 seconds for may
calculation is I want a precision of 1%.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
