Interesting that branching is now better supported and almost free. I wonder if merging can be simplified or whether it already is as simple and as fast as it can be?

I guess I am inspired by Dolt’s ability to branch and merge: https://github.com/dolthub/dolt

  Bringing copy-on-write semantics to PostgreSQL.

https://github.com/Photonios/pgcow that supports ZFS.

BTRFS is not that scary. Quota and RAID56 is broken but other features have been stable quite some time. Btrfs is used by default for few Linux distros and Facebook makes quite heavy use of it on their servers https://lwn.net/Articles/824855/

I have been running btrfs on all of my machines since 2016 as transparrent file compression helps a lot with keeping disk usage down.

Btrfs RAID1 even saved my data once when one of the SSD's decided to die suddenly.

For maximum performance you should run databases on top of XFS anyway. It also supports per-file COW via relinks.

• pg-clone-schema

  3 158 8.1 PLpgSQL

  Postgres clone schema utility without need of going outside of database. Makes developers life easy by running single function to clone schema with all objects. It is very handy on Postgres RDS. Utility is sponsored by http://elephas.io/

For ad hoc copies I’ve found the third party schema cloning function useful. I assume performance would be an issue for huge databases though. https://github.com/denishpatel/pg-clone-schema
