PostgreSQL: Extra security measures for next week's releases

The core committee has decided that one of the security issues due to be fixed next week is sufficiently bad that we need to take extra measures to prevent it from becoming public before packages containing the fix are available. (This is a scenario we've discussed before, but never had to actually implement.)

What we intend to do is shut off updates from the master git repo to the anonymous-git mirror, and to github, from Monday afternoon until Thursday morning. [...] This will prevent the commits that fix and document the bug from becoming visible to anyone except Postgres committers. Updates will resume as soon as the release announcement is made.
