Comment 4 for bug 422189

Argh, this was a regression from:

revno: 758
committer: Martin Pitt <email address hidden>
branch nick: postgresql-common
timestamp: Sun 2007-05-20 13:36:59 +0200
message:
  * pg_createcluster, pg_ctlcluster, pg_dropcluster, pg_maintenance,
    pg_upgradecluster: Strip down PATH untainting to the absolute minimum, to
    not fall over if e. g. /usr/local/bin is misconfigured to be world
    writable. Closes: #420565

Odd, that's two years old, and nobody noticed so far, thanks for pointing out.

This is not an issue any more in Ubuntu 9.04 and 9.10, since the cron job and pg_maintenance are completely gone (thanks to the internal autovacuum in PostgreSQL 8.3 and onward).
