Seems to be some resistance to getting this in core, so why not just use an extension? I was able to create a quick POC to do just that. Hook into PG and look for AlterSystemStmt, throw a "Sorry, ALTER SYSTEM is not currently allowed" error. Put into shared_preload_libraries and you're done. As a bonus, works on all supported versions, so no need to wait for Postgres 17 - or Postgres 18/19 given the feature drift this thread is experiencing :)

Cheers,
Greg
