I manage some PostgreSQL clusters on Linux. We have a Primary & two Standby
servers & for Production, there is also a DR server. We use repmgr for our HA
solution & the Standbys are cloned from the Primary using the repmgr standby
clone command.

Hi,
imagine I have a database containing normalized data: a whole bunch
of tables all related via foreign keys (i.e. the thing one should
usually have ;) ).
So there is a dependency graph: all records relate to others in
some tree-like fashion (has-many, belongs-to, etc.)
Now I want to grab

I wanted to understand the underlying issue.
I use ZFS snapshots instead of a “correct” backup because with only two
machines it allows me to have backups in the main machine and in the secondary
