upgrade proc with pitr standby

What are the steps for upgrade of a primary/PITR standby pair to the
latest 8.3 patchset, 8.3.6-8.3.10? I don't see this in the docs.
Should there be something added to 15.4. Upgrading?

My guess is:
1. turn off the standby config in primary
2. upgrade primary
3. rebuild standby

That way you don't loose the standby if something goes in the toilet.
Is that right?

You need to upgrade standby first, restart it. Then, upgrade master and
restart it. No need to turn off standby config.

Return code 32512? I think you'd be OK if your recovery script
returned 1 when it didn't find this file.

Tom wrote last year:

Hmm ... 32512 is 0x7F00, which I think means exit(127), which is
generally what the shell returns when it can't find the program
it's supposed to execute.
