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. Commit-log emails to pgsql-committers will also be

held for this period. 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.

Although committers will still be able to work normally, we realize

that this is likely to be a handicap for non-committers; and it will

also mean that buildfarm runs will not test any new commits until the

mirrors are allowed to update. We do not intend to start doing this

as a routine thing, and apologize in advance for any disruption.

It seems necessary in this instance, however.
