Comment 9 for bug 874296

So I found a few last minute functions that also needed changing over to native use. Please double check my work on the string_agg() changes in one of the new commits.

The other commit included in my branch is a first crack at the upgrade script that replaces all the functions, etc. that were altered. At the end of the script, I included some echo comments explaining that people should re-run their example.reporter-extension.sql script to get the latest changed versions there too.
