Postgres 8.2.6-2

Hopefully, I’ve fixed a couple problems that would cause the postgres user creation and data store initialization to fail. It’s difficult for me to test because it has always worked for me, but I did identify and correct a couple possible sources of the problem.

If you have already installed Postgres 8.2.6-1 and it is running, there is no need to 8.2.6-2.
