The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/13/datatype-numeric.html Description:
> The actual storage requirement is two bytes for each group of four decimal digits, plus three to eight bytes overhead. Please describe what 'overhead' means. I'd like to be able to calculate the data size of NUMBER(19,4). I can calculate 2 bytes per 4 digits... with 19 digits, I have 5 groups of 4 digits, so the data length I seek is 5 bytes + overhead... then I'm left hanging. :( Troy. #
