Point well taken. And when I said 'I completely understand that', I meant I
understood Postgres' policy for patching older releases. And thanks for the
links; it feels good to know that there's an "official" stand on this topic
in Postgres, rather than 'no known serious bugs'. :)

I am still looking for comments on the correctness of this script and above
mentioned procedure for running it on an 8.2.x release.

Thanks and best regards,
