Hello,

I'd like to convert a string number to a number being able to provide the custom format.

With dates it works perfectly fine, so that I can do:

SELECT to_date('18 09 10', 'YY MM DD')

Is there something similar with numbers?

SELECT to_number('9,000',some_format) =9;

 SELECT to_number('9,000', '9V3')::int;
 to_number
-----------
         9

SELECT to_number('9,000',another_format) =9000;

SELECT to_number('9,000', '99999');
 to_number
-----------
      9000

It is not clear to me what some_format should be and what another_format should be so that those selects are equal.

I've read the documentation but I can't find a similar example. In stackoverflow they don't provide a solution either: https://stackoverflow.com/questions/18882942/postgresql-convert-a-string-with-commas-into-an-integer
