Thread: Possible Bug in pg_upgrade
Beginning with commit 002c105a0706bd1c1e939fe0f47ecdceeae6c52d pg_upgrade will fail if there are orphaned temp tables in the current database with the message 'old and new databases "postgres" have a different number of relations' On line 41 of pg_upgrade/info.c pg_upgrade checks that the number of relations are the same but includes orphaned temp tables in the comparison. Is this expected behavior? If so is there a more detailed error message that can be added explain the cause of the failure? It wasn't evident until modified pg_upgrade to show the missing oid's and recognized them as temp tables with oid2name.

Seems like an oversight.
regards, tom lane
Attached is a patch that skips orphaned temporary relations in pg_upgrade if they are lingering around. It works for
9.0-> 9.1 upgrades, however I wasn't able to tell when pg_class.relistemp was added so if it was unavailable in
versionsprior to 9.0 an additional check will have to be added.
Thanks

I'm inclined to think the correct fix is to revert the assumption that
the old and new databases contain exactly the same number of tables ...
that seems to have a lot of potential failure modes besides this one.

It's basically checking whether pg_dump -s worked. That doesn't seem like a good use of time.

It is certainly is a corner case but it bit me when preparing for the upcoming 9.1 release. I would imagine others will hit it as well.

Thanks for your report and patch.
Let me give some background on pg_upgrade to explain what is happening.
Pg_upgrade uses two C arrays to store information about tables and
indexes for the old and new clusters. It is not possible to store this
information in a database because both clusters are down when pg_upgrade
needs to use this information.
In pre-9.1 pg_upgrade, pg_upgrade did a sequential scan of the arrays
looking for a match between old and new cluster objects. This was
reported as slow for databases with many objects, and I could reproduce
the slowness. I added some caching in 9.0 but the real solution for 9.1
was to assume a one-to-one mapping between the old and new C arrays,
i.e. the 5th entry in the old cluster array is the same as the 5th
element in the new cluster array.
I knew this was risky but was the right solution so it doesn't surprise
me you found a failure. pg_upgrade checks that the size of the two
arrays in the same and also checks that each element matches --- the
former is what generated your error.
Now, about the cause. I had not anticipated that orphaned temp objects
could exist in either cluster. In fact, this case would have generated
an error in 9.0 as well, but with a different error message.
Looking futher, pg_upgrade has to use the same object filter as
pg_dump, and pg_dump uses this C test:
pg_dump.c: else if (strncmp(nsinfo->dobj.name, "pg_", 3) == 0 ||
pg_dumpall uses this filter:
"WHERE spcname !~ '^pg_' "
The problem is that the filter used by pg_upgrade only excluded
pg_catalog, not pg_temp* as well.
I have developed the attached two patches, one for 9.0, and the second
for 9.1 and 9.2 which will make pg_upgrade now match the pg_dump
filtering and produce proper results for orphaned temp tables by
filtering them.
As far as unlogged tables, those are dumped by 9.1/9.2, so there is no
need to check relpersistence in this patch. pg_dump doesn't check
relistemp either.
