Shrink UUIDs with PostgreSQL or Ruby
Unfortunately, as of PostgreSQL 16, UUIDv7 are not yet supported out of the box. For the time being, use an extension such as pg_uuidv7 or pg_idkit to generate UUIDv7 e.g. as default primary key when you CREATE new records.

UUIDv7 is coming in PostgreSQL 17
https://github.com/fboulnois/pg_uuidv7
It's slightly different from recommendations by draft RFC version (there's no counter), but fully within spec requirements. From practical point there's no difference at all.

UUIDs are obsolete in the age of Docker
Sometimes, I am amazed about what gets on the front page of ycombinator.
TLDR: Don't use UUID v1, since its entropy is based on the Mac address, if your cloud provider is generating the same mac addresses for all your containers.
To say not use UUID's it makes no sense. Use UUIDv7, use them in postgres https://github.com/fboulnois/pg_uuidv7 have fun :)

Are there trusted non-cryptographic hashing extensions for Postgresql?
I have also found some random Github repositories like pghashlib and pg_xxhash but they don't seem super popular and I'm hesitant to use them in a production system (pg_xxhash specifically disuades from using it in a serious system).
What are some alternatives?
When comparing pg_uuidv7 and pg_xxhash you can also consider the following projects:
pg_math - pg_math extension to support statistical distribution functions for PostgreSQL
pghashlib - Stable hash functions for Postgres
