As of late I have been looking at large numeric values in my data, to include file , row count, and index sizes. These can drift into terabytes or tens of billions of rows.
It would be nice to have the numbers displayed to be broken up with a regionally (or language specific) friendly character or user preference.
For me that would the be the comma (18,990,752,384).
For others it might be the period (18.990.752.384)
It makes it easier to visualize the meaning / scale of the number quickly.
This could be a toggle-able user lever option.
One tool that does this is (I think) DBeaver. Copy to clipboard strips these for simplicity, but that is a desktop application.
