Hi guys.
I see these every now and again:
2023-12-19 08:43:17.311 CET [2494773] FATAL: highest
timeline 105 of the primary is behind recovery timeline 106
and the only thing I can think is a backup which in my case
it a done with _libvirt_ as pgSQL cluster runs on Ubuntu VMs.
I'm not sure what exactly _virsh backup-begin_ does to the
qcow2 and as a consequence, to the the FS in the VMs, but..
it would be good to have those backups.
Any thoughts & ideas shared are much appreciated.
I guess my first question would be -- if such VM backup
might affect negatively pgSQL then, are there some tweaks,
ways to harden pgSQL cluster internally for such scenarios?
many thanks, L.
