Apply all 2.2 upgrades prior to running 2.3.0 upgrade

If users are expected to run all of the 2.2 upgrade scripts, then let's
make it easy for them. As PostgreSQL 9.1 does not include the \ir
"include relative path" command, we have to pause at the beginning of
the upgrade process to ensure that the user is running the script from
the right directory.
