:cough: So it's been 10 years.
This is a horrendous design flaw for a piece of software that calls itself a database.
Ignoring that 64-bit is hardly new or controversial, even at that time, or that it even represents any form of onus on IT…
In relation to errors passing silently, there's a giant warning displayed if you attempt to utilize the 32-bit version, and it's been there for a very long time, plus red flags of warning on the download page and documentation relating to it. Similar to the warning emitted if it detects you have THP (Transparent Huge Pages) enabled in your kernel, which violates assumptions over memory pages being 4KiB and the performance guarantees of allocation operations.
If you tell a database to store something, and it doesn’t complain, you should safely assume that it was stored.
