Hey Tom,
Had a small query here.
If we have streaming replication enabled, and if we have corruption like this due to power loss etc,
is it safe to assume we failover to standby and we should be good (atleast in most cases)
I wanted to understand if the system catalog is corrupted, for some reason, will it/will it not stream replicate the
corrupteddata to standby.
Or they are a property of an individual database server and will be rebuilt/updated on pg_dump/restore.
I am sorry if I am diverting the Drako's query or if that is not related, I'll ask another question then __
But I guess maybe the answer may help Drako too.
Thanks,
Vijay

This suggests you've actually lost some entries from pg_proc. Have
you had any system crashes or suchlike?

No, pg_upgrade can't magically restore data that's not there.
