Hi Joel, Here are my two cents.
> 1. Who are the current users of 32-bit PostgreSQL? Pretty much any embedded system that uses just a few GB of memory may win from using a 32-bit processor (not necessarily in terms of performance, maybe in terms of price). Think of WiFi-routers, smart TVs, 3D printers, etc. Generally speaking it's hard to give an exact answer due to lack of "telemetry" in PostgreSQL. > 2. Among these users, how many are upgrading to new major versions? I would guess it very much depends on the product and manufacturer. I wouldn't assume though that users of 32-bit systems don't do major upgrades. (Not to mention that it's beneficial for us to test the code on 32-bit systems.) > 3. For how many of these users is performance critical? Depends on how you define performance. Performance of a single OLTP query is important. The performance of the upgrade procedure is probably not that important. The ability of processing a lot of data is probably also not extremely important, at least I wouldn't expect a lot of data and/or fast storage devices on 32-bit systems. -- Best regards, Aleksander Alekseev
