Re: v8.3.4 metadata changes while users active

I'll be running this as "postgres"
Thanks for the help.
Hope others may find this useful.

Yep. That should work. The only reservation I'd bring up here is that you
should be doing this as a user other than one of those two users. Otherwise
you may lock yourself out of the DB. I assume you'll be doing this as either
a PG superuser (e.g. postgres) or a user distinct from the two above.
