Hello,

We are using v6.3.2 with patches, and using many tables which
uses 'large object'.  Main problem with it is

(1) cannot dump large object,  is this still true in v6.5.1 ?
      or no plan for immplementing dumping blobs in near future?
(2) if I want to clone dbs from linux to solaris machine, due to the above
     lo & pg_dump problem, lots of manual works needed to dump dbs
     -> restore to another architecture machine...  Is there any utility
     to ease duplication(backup) of dbs?
(3) to upgrade v6.3.2 dbs to v6.5.1, including large objects, is there
      ways to dump/restore?

Another problem with v6.3.2 is frequent messages(error?) related to
the backend cache invalidation failure -- probably posted many times...
like this:
       NOTICE:  SIAssignBackendId: discarding tag 2147430138
       Connection databese 'request' failed.
       FATAL 1:  Backend cache invalidation initialization failed
(1) Increasing max connection # from 32 to 64 in
      src/include/storage/sinvaladt.h will simply fix above problem?
(2) If I want to keep v6.3.2, which PATCH will FIX above problem?
(3) already fixed in v6.5.1?

Best Regards,
