While this is not a direct answer to question..

It made me think. I am sure lot of people have lot of functions written in
order to get job done. Can we have an archive of such functions, if authors are
willing to make it open.

Something like CPAN? Yeah we don't need to change that name..:-)

Hi,

if didn't find this function on
http://www.postgresql.org/docs/7.3/interactive/functions-datetime.html,
You have to write own function

testdb=> create or replace function last_day(date) returns date as 'select
cast(date_trunc(''month'', $1) + ''1 month''::interval as date) - 1'
language sql;
CREATE FUNCTION
testdb=> select last_day(current_date);
  last_day

I also have a small, but growing collection of *stuff*
off of the General Bits site as well as a number of
useful functions with explanations in lots of articles.

Search with local google or look through tidbits
and the Archives.
