> What 32-bit systems are being used today?

I found these in the PostgreSQL Build Farm:

- AIX 7100-05-06-2028 gcc 8.3.0 (32 bit) ppc64 (POWER7) - Debian 7.0 gcc 4.7.2 i686 - Debian Sid gcc recent i386

But there might be more that we don't know about.

Any of the supported platforms: x86, PowerPC, (S/390), SPARC, ARM, MIPS, RISC-V, and PA-RISC

No, it's when running PostgreSQL on actual 32-bit hardware.
