AFAIK, Tom have fixed it, if this bug is about -funsigned-char

JDBC doesn't support cursors full stop yet.

No as it's obsolete in 7.1 ;-)

Client code not calling Connection.close() method.

Removed from list.  Doesn't even seem worth adding to TODO.

Removed.  ODBC seems to have a problem, though.

Thanks.

Ok. I have made patches for fixing some of pg_dump problems(see
attached patches). The patches address the problem with user defined
functions, operators and aggregates. Could someone please review and
commit them if they look ok?  (I'm now in US and have only very
expensive internet connection through an international phone call to
Japan in a hotel! Also I'm not quite sure "#arg" (stringification) is
portable enough in all platforms.)  Or I could commit after going back
to Japan planned on Feb 2 if that's not too late.

However I have not address what Tom Lane said yet(actually I do not
understand what he says).

These have now been applied with minor modifications.

This refers to things like:

        SELECT c.relname
        FROM pg_index i, pg_class c
        WHERE i.indrelid = %s
        AND   i.indisprimary
        AND   c.oid = i.indexrelid

ie. where two or more relations are crossed (pg_index and pg_class in this
case). It assumes that the metadata is valid, and will not highlight
missing data in the secondary table. We should be doing outer joins:

        SELECT c.relname
        FROM pg_index i LEFT OUTER JOIN pg_class c on c.oid = i.indexrelid
        WHERE i.indrelid = %s
        AND   i.indisprimary

and checking for nulls using PQgetisnull. I have actually done this for a
couple of SELECTs (including the above one), and marked all the others as
'XXXX: use LOJ'. There are only 2 or 3 more, but they require a little more
thought (an inderstanding) before I change them.

In my view this should be considered a 'work-in-progress' and not hold up
7.1 since the problem has been there for a long time.

Thanks. BTW, are you going to make a back patch for the 7.0.x tree?
I'm sure we are going to have lots of complaints from users who are
developing their own user defined functions and about to use pg_dump
to upgrade to 7.1 after it is officially released...

Sorry for the delay, but this set of patches were targetted at trapping bad
metadata and as such are probably not appropriate for backporting. However,
some months ago, Tom did modify pg_dump for the new function manager
interface. It might be worth making a backpatch for this available.
