allows unprivileged users to crash the server, if it has been compiled with
Asserts enabled.  The escalation-of-privilege risk exists only in 8.1.0-8.1.2.
However, the Assert-crash risk exists in all releases back to 7.3.

  While playing with this patch under 8.1.2 at home I discovered a
  mistake in how I manually applied one of the hunks to fe-auth.c.
  Basically, the base code had changed and so the patch needed to be
  modified slightly.  This is because the code no longer either has a
  freeable pointer under 'name' or has 'name' as NULL.

  The attached patch correctly frees the string from pg_krb5_authname
  (where it had been strdup'd) if and only if pg_krb5_authname returned
  a string (as opposed to falling through and having name be set using
  name = pw->name;).  Also added a comment to this effect.
  Please review.

I looked into this and it seems the problem is that the view doesn't
get flattened into the main query because of the has_nullable_targetlist
limitation in prepjointree.c.  That's triggered because pg_roles has
        '********'::text AS rolpassword
which isn't nullable, meaning it would produce wrong behavior if
referenced above the outer join.

Ultimately, the reason this is a problem is that the planner deals only
in simple Vars while processing joins; it doesn't want to think about
expressions.  I'm starting to think that it may be time to fix this,
because I've run into several related restrictions lately, but it seems
like a nontrivial project.

In the meantime, reducing the LEFT JOIN to pg_roles to a JOIN as per
Peter's suggestion seems like the best short-term workaround.

Ok, so *that's* where the bit about the query plan being simple enough.
Based on that, ISTM that it should be premissable for us to decide that
a cursor requiring a sort isn't "simple enough" to support SCROLL.

In any case, here's a patch that makes the non-standard behavior easier
for people to find.

--enable-depend it often tries to create the .deps directory twice and
bails out when it already exists due to a race condition of if doesn't
exist, then create.  This patch prevents mkdir from returning an error.

consistently.  This is mostly cosmetic right at the moment because
check_assignable() does nothing for ROW or RECORD datums, but that might
not always be so.  This also syncs several different places that read
INTO target lists.  They're just enough different that it seems
impractical to factor them into a single routine, but they surely
should be the same as much as possible.

comments on cluster global objects like databases, tablespaces, and
roles.

It touches a lot of places, but not much in the way of big changes.  The
only design decision I made was to duplicate the query and manipulation
functions rather than to try and have them handle both shared and local
comments.  I believe this is simpler for the code and not an issue for
callers because they know what type of object they are dealing with.
This has resulted in a shobj_description function analagous to
obj_description and backend functions [Create/Delete]SharedComments
mirroring the existing [Create/Delete]Comments functions.

This is mostly just over-compulsiveness on my part, but the exercise
did reveal one real bug: errors.out has a space difference now where
it should not.

(optionally) to a new host and port without exiting psql.  This
eliminates, IMHO, a surprise in that you can now connect to PostgreSQL
on a differnt machine from the one where you started your session. This
should help people who use psql as an administrative tool.

during the vacuumcleanup scan that we're going to do anyway.  Should
save a few cycles (one calculation per page, not per tuple) as well
as not having to depend on assumptions about heap and index being
in step.
I think this could probably be made to work for GIST too, but that
code looks messy enough that I'm disinclined to try right now.
