ERRORs after upgrade from 7.2.1 to 7.4 about nonexisting large objects

Hi,

sorry for reposting, but it seems my message just hit nothing
but air. If I posted to the wrong list or did something else
wrong with the message, please let me know.

I really want to know what's going on but still found nothing.
I do not know when and where the statements are produced that
lead to the error messages. It seems they were generated by
postgres internally but I cannot see when and why. How can
I find out? I want to stop those errors.

Hi all,

a few days ago, I upgraded from PostgreSQL 7.2.1 to 7.4, following
the instructions in the INSTALL file, including dump and restore.
All this worked fine without any error (message).

Since then, I found lots of the following in the postmaster output:

2003-11-29 15:19:54 [1359] ERROR: large object 4838779 does not exist

I cannot find the source of those errors. It seems that everything is
basically working, but there are always those errors about the two
large objects.
I'd like to find out what went wrong and how I can repair it. I couldn't
find anything in the docs and the mailing lists.

To give more information about the messages, here are two more detailed
outputs, one per id:

The logged statements seems to suggest that there went something wrong with
the template database creation or maybe the dump/restore. But as I wrote
earlier: There was no visible error.
