Today, by chance, we were able to trigger a bug new to v7.0, dealing with
indices on system tables ...

Tom Lane quickly generated and applied patches for this, and we've created
a Release Candidate 5 based on these patches ...

This RC *requires* a complete dump/initdb/reload of your database
... without it, consider your database a ticking timebomb ...

The Release Candidate is available in its usual location:

	ftp://ftp.postgresql.org/pub/...

Or at least your pg_group table is a timebomb, if it's not empty.
Panic is not called for unless you use groups.

It should be noted that we found and fixed some problems in pg_upgrade
as well.  This may mean that pg_upgrade is now safe.  Or not, but it's
hard to say without testing.  I would like to ask people who are
upgrading to RC5 to try to use pg_upgrade for the move, and report
whether you see problems or not.  *Please* read the man page for
pg_upgrade, and make a complete dump beforehand so you have a fallback
if it fails ...

			regards, tom lane

Nope, could have gone with something like "a nuclear bomb just itching to
explode", but thought it was too verbose :)
