Answer 1

This video I made a while back goes over several format options including what you are looking for: https://www.youtube.com/watch?v=d3f3fvMGDnU
If you add the -t option, it will not show you how many rows are returned or the column headers. Looks like you are already using the -A option, so adding the -t option should be all you need to create properly delimited file contents.

Answer 2

You need to switch output on and off within the script.
Preparing the table:
CREATE TABLE public.aks AS
WITH
-- need a series of integers ..
i AS (
SELECT MICROSECOND(ts) AS i , 'slartibartfast' AS name FROM (
SELECT TIMESTAMPADD(microsecond, 1,'2000-01-01'::TIMESTAMP) AS tm UNION ALL
SELECT TIMESTAMPADD(microsecond,100,'2000-01-01'::TIMESTAMP) AS tm
)x
TIMESERIES ts AS '1 microsecond' OVER(ORDER BY tm)
)
SELECT * FROM i;
Once that is done - the script looks like this:
-- send all output to nirvana
\o /dev/null
UPDATE public.aks SET name='Akshay';
-- send output back to screen
\o
SELECT 2;
SELECT 3;
SELECT 4;
And the output:
2
3
4
Is this what you're looking for?
