Re: populate value of column

I believe they are standard PostgreSQL functions – not sure what version
they appeared in though.

I learnt about them by RTM

I even tested this one too ;)
SELECT meter_id,
LPAD(GENERATE_SERIES(1,area_no),2,'0')
FROM meter;

Works on 8.2.4 - you didn't say what version you were using.
