Upgrade 7.0.2 -> 7.1.2: Errors during Restore

On my Red Hat Linux 6.2 box, I just upgraded from 7.0.2 to 7.1.2.  I used the
7.0.2 pg_dumpall, and after moving the 7.1.2 installation into place, firing up
postmaster, and running initdb I restored my pg_dumpall output.

The results of the restore seem to be fine, but there were a number of errors
during it and I want to make sure they're harmless.  My guess is they are,
especially since they didn't take place within the areas of the dump file where
my data was located.  A number of them seem to be throwbacks to 7.0RC1, based on
the path given in the messages.

I've pulled all the error messages and put them below.  Many of them regard
failure to stat regress.so, and then there are a variety of other ones regarding
nonexistent functions, etc.

I'd just like to know if I need to be concerned or not.

Thanks,
Jim
