Right. I know there were multiple issue with this upgrade, jails
probably being the biggest, but a new one I had never heard is that _if_
you are placing your tablespaces in the PGDATA directory, and you are
upgrading from pre-9.2, if you rename the old data directory, you also
need to start the old server and update pg_tablespace.spclocation.
Just to have it on the record. I did the upgrade outside of the jail to make sure. I also tested it within jails and it worked also.
