That's complaining about two tuples in the pg_largeobject table with
xmin values that precedes relfrozenxid -- which suggests that even
after 80d6907219, relfrozenxid isn't being correctly preserved in this
test case, since the last run still failed the same way.
But what exactly is this test case testing? I've previously complained
about buildfarm outputs not being as labelled as well as they need to
be in order to be easily understood by, well, me anyway. It'd sure
help if the commands that led up to this problem were included in the
output. I downloaded latest-client.tgz from the build farm server and
am looking at TestUpgradeXversion.pm, but there's no mention of
-amcheck-1.log in there, just -analyse.log, -copy.log, and following.
So I suppose this is running some different code or special
configuration...
