>> Or maybe use "sed" to strip out the -reuse-previous options from pg_dumpall's output
Removing " -reuse-previous=on" from the pg_dumpall file worked. I still would like to upgrade to 9.2. As with my prior email, if there is a recipe of sorts for upgrading pg8.4 to pg9.2 that would be great.
Thanks

Ah. That option was introduced quite recently as part of a security fix.
It's no surprise 8.x doesn't recognize it.
You could probably work around this by using pg_dumpall with -g to just dump roles and tablespaces, and then pg_dump'ing individual databases separately. A mite tedious and error-prone. Or maybe use "sed" to strip out the -reuse-previous options from pg_dumpall's output. But really this is the best answer, because 8.x is long out of support:

I searched for some time on how to do this and every tutorial does it a little different and each has different steps that the others do not have. Is there a clear step by step procedure to do this upgrade?
If you're working with locally-built copies of Postgres, I'd say just follow the recipe given in the pg_upgrade man page. If you are working with someone's packaged version of Postgres, the packager may have provided a script or something for upgrades, in which case follow their recommendation. Either way it's a good idea to make a backup beforehand in case of disaster.
