and summing up the values of 10 ids takes about 2.5
seconds, which looks to me like a quite a nice performance.

That field of yours... what type is it?
Is it TEXT? is it a numeric type?
If it's TEXT, why don't you make it say... NUMERIC(/10/, /6///)?

2 is a constat that stands for the '0.' part of the string
representing the decimal part of the number.

For the record if you'd like to use regexp:
select substring('201.123' from $$[0-9]*$$);
and
select substring('201.1232' from $$\.([0-9]*)$$);

2 is a constat

Hi,
I want to display data for all days in a month even if no data
exists for that month. Some of the days in a month might not have
any data at all. With normal query, we can display days only if
data exists.But I want to display rows
. The immutable
property is used top determine if it's safe to use indexes or other
plans that avoid evaluating an expression repeatedly.

Is this the recommended way to proceed?
Thank you!

Hi all, is there a way to define functions and/or triggers in a
function?
For example, can I create a function that takes an argument and
defines a function that has the name passed as argument
comparison?
What would it be the fastest way of correctly implementing comparison
operators for the DATE type?
Thank you very much in advance,
