I think this would be a great solution. The message is easy to find and
the instructions are easy to follow.

I suggest maybe using "Note" instead of "Caution" because otherwise it
sounds quite dangerous and maybe we want to reserve that for when we
have some serious things to report. Also I suggest writing "PostgreSQL
CI is disabled ...", not just "CI is disabled ...", since that might
otherwise be confusing, especially since this is being considered in the
context of downstream forks that were not expecting this. (I also
considered "PostgreSQL community CI ..." to be even more explicit.)

Since you made a point of reordering dependencies, the
${MINGW_PACKAGE_PREFIX}-zstd is not quite in the right place.

This seems useful. Otherwise, if you have a private fork and just want
to park some patches, this will blow through your private repository
free credits in about 5 or 6 builds. (Learned that a few days ago. ;-) )
