Tom, thanks for the quick reply.
Unfortunately, rebuilding the backup server from the master is not really an option at this point. This is a fairly large database (~1TB), are there any other options that will allow us to get the backup server to ingest WAL files without database corruption?
Thanks,
Scott

recommend it, because you wouldn't just end up with "lost" data, you'd
end up with corrupted data. Indexes in particular would probably be
unusably inconsistent, leading to wrong answers, occasional PANICs
on the backup server, etc.
I'd recommend re-syncing the backup to the master using a fresh base
backup. Yeah, it's more work, but you'll have an actual backup not
a useless pile of inconsistent bits.
