Re: question on most efficient way to increment a column

In some cases, it would be 2-10 times a second per id.

How often are these updated? Once an hour, once a minute, once a
second, a thousand times a second?

If it's not more than once a second I would look at eager materialized
views as a possibility for handing this.
