Problem with pg_upgrade - Mailing list pgsql-bugs

Hello,

I am trying to use pg_upgrade to upgrade data from 9.1.4 to 9.2beta2.
Although the upgrade completed successfully,  vacuumdb --all --analyze-only
gives an error. I tried upgrading two binary backups of the same production
database from different days, and both returned the exact same error . The
output I got for both trials is as follows:

First trial:


   1. postgres@sparedb1:/data/pg$ sh analyze_new_cluster.sh
   2. This script will generate minimal optimizer statistics rapidly
   3. so your system is usable, and then gather statistics twice more
   4. with increasing accuracy.  When it is done, your system will
   5. have the default level of optimizer statistics.
   6.
   7. If you have used ALTER TABLE to modify the statistics target for
   8. any tables, you might want to remove them and restore them after
   9. running this script because they will delay fast statistics
   generation.
   10.
   11. If you would like default statistics as quickly as possible, cancel
   12. this script and run:
   13.     vacuumdb --all --analyze-only
   14.
   15. Generating minimal optimizer statistics (1 target)
   16. --------------------------------------------------
   17. vacuumdb: vacuuming database "functionx"
   18. vacuumdb: vacuuming database "postgres"
   19. vacuumdb: vacuuming of database "postgres" failed: ERROR:  could not
   access status of transaction 46675125
   20. DETAIL:  Could not open file "pg_clog/002C": No such file or
   directory.
   21.
   22. The server is now available with minimal optimizer statistics.
   23. Query performance will be optimal once this script completes.
   24.
   25. Generating medium optimizer statistics (10 targets)
   26. ---------------------------------------------------
   27. vacuumdb: vacuuming database "functionx"
   28. vacuumdb: vacuuming database "postgres"
   29. vacuumdb: vacuuming of database "postgres" failed: ERROR:  could not
   access status of transaction 46675125
   30. DETAIL:  Could not open file "pg_clog/002C": No such file or
   directory.
   31.
   32. Generating default (full) optimizer statistics (100 targets?)
   33. -------------------------------------------------------------
   34. vacuumdb: vacuuming database "functionx"
   35. vacuumdb: vacuuming database "postgres"
   36. vacuumdb: vacuuming of database "postgres" failed: ERROR:  could not
   access status of transaction 46675125
   37. DETAIL:  Could not open file "pg_clog/002C": No such file or
   directory.
   38.
   39. Done
   40. postgres@sparedb1:/data/pg$

Second Trial:


   1. postgres@sparedb1:/data/pg$ /opt/pgbrew/9.2beta2}/bin/pg_upgrade -d
   /data/pg/9.1 -D /data/pg/9.2 -b /opt/pgbrew/9.1.4/bin -B /opt/pgbrew/9
   .2beta2}/bin
   2. Performing Consistency Checks
   3. -----------------------------
   4. Checking current, bin, and data directories                 ok
   5. Checking cluster versions                                   ok
   6. Checking database user is a superuser                       ok
   7. Checking for prepared transactions                          ok
   8. Checking for reg* system OID user data types                ok
   9. Checking for contrib/isn with bigint-passing mismatch       ok
   10. Creating catalog dump                                       ok
   11. Checking for prepared transactions                          ok
   12. Checking for presence of required libraries                 ok
   13.
   14. If pg_upgrade fails after this point, you must re-initdb the
   15. new cluster before continuing.
   16.
   17. Performing Upgrade
   18. ------------------
   19. Analyzing all rows in the new cluster                       ok
   20. Freezing all rows on the new cluster                        ok
   21. Deleting new commit clogs                                   ok
   22. Copying old commit clogs to new server                      ok
   23. Setting next transaction ID for new cluster                 ok
   24. Resetting WAL archives                                      ok
   25. Setting frozenxid counters in new cluster                   ok
   26. Creating databases in the new cluster                       ok
   27. Adding support functions to new cluster                     ok
   28. Restoring database schema to new cluster                    ok
   29. Removing support functions from new cluster                 ok
   30. Copying user relation files
   31.                                                             ok
   32. Setting next OID for new cluster                            ok
   33. Creating script to analyze new cluster                      ok
   34. Creating script to delete old cluster                       ok
   35.
   36. Upgrade Complete
   37. ----------------
   38. Optimizer statistics are not transferred by pg_upgrade so,
   39. once you start the new server, consider running:
   40.     analyze_new_cluster.sh
   41.
   42. Running this script will delete the old cluster's data files:
   43.     delete_old_cluster.sh
   44. postgres@sparedb1:/data/pg$ echo $PATH
