As a quick reference point, I spent a few minutes looking at how the
PostgreSQL Yum Repository handles architectures and distributions. It
looks like when a repo is EOLed, they stop providing updates to any
package except PostgreSQL RPMs [1]. Additionally, it looks like RHEL 6
was the last distribution to support x86.
Looking at the current release notes for Debian trixie [2], i686 will
still be an officially supported architecture. I think the proposal to
continue building the server, but disable building all extensions for
32-bit architectures is very reasonable.
