I have a column »timestamp with time zone«. I want to extract the date/time in
a different format including the time zone offset in a query but without
seconds. If I do
select to_char(datetime, 'YYYY-MM-DD HH24:MI') from table;
then the time zone offset is missing in the output: 2011-03-25 18:01
If I do
select date_trunc( 'minute', datetime) from table;
then the time zone offset is present, but the seconds are not removed:
2011-03-25 18:01:00+01
I want it to look like this: 2011-03-25 18:01+01
How to do that?

There are the TZ and tz formats but they return abbreviated names, not
offsets. It's a tiny kludge, but this should do what you want:
to_char(now(), 'YYYY-MM-DD HH:MM') || to_char(extract(timezone_hour from
now()), 'S09')
This is based on the assumption that you will never have to deal with
timezones that have other than whole-hour offsets:
select * from pg_timezone_names where utc_offset::text !~ '00:00';
Cheers,
Steve
