satori uuid vs google uuid vs gofrs uuid ? which to use to generate uuid for enterprise coding standards
https://github.com/gofrs/uuid upto v5

Any way of blocking or preferring a package?
I use Google's UUID package a lot. But every time I refer to it in a new package, the language server picks up https://github.com/gofrs/uuid instead of https://github.com/google/uuid and then complains that the gofrs package isn't in go.mod. I assume because it's the first alphabetically (though this seems like a huge supply chain security loophole).

cmackenzie1/go-uuid: library for generating version 4 (random) and version 7 (time-ordered) UUIDs
What makes this different than https://github.com/gofrs/uuid ?

Building web-based SaaS with Go as a solo entrepreneur. What should I be aware of?
Something to note is that all of this is still open source. Theoretically, someone can decide to fork SQLBoiler and add all the missing things, or send in a PR. A good example is that the current most popular uuid package. gofrs/uuid was forked from an unmaintained previously popular package.

Which UUID package do you use? and why?
You could also look at github.com/gofrs/uuid which includes support for v6 and v7 from the latest draft UUID spec. Personally I think the API for this library is nicer since the google one makes it difficult to tell what kind of UUID you are generating.

Example Golang RESTful API (Fully Containerized Local Development)
Postgres has native UUID support so don't use VARCHAR(36). Look at https://github.com/gofrs/uuid library, among others, to create uuid.

CVE-2021-3538 issued for latest release of github.com/satori/go.uuid
If you're using this library and are unsure what to do, a few of us maintain a fork of this library that has fixed these issues (and others): https://github.com/gofrs/uuid

Zero Downtime Postgres Upgrades
OP here - we avoid sequences in all but one part of our application due to a dependency. We use [KSUIDs][1] and UUID v4 in various places. This one "gotcha" applies to any sequence, so it's worth calling out as general advice when running a migration like this.

Bye Sequence, Hello UUIDv7
UUID v4 isn't large enough to prevent collisions, that is why segment.io created https://github.com/segmentio/ksuid which is 160bit vs the 128bit of a UUIDv4.

Type-safe, K-sortable, globally unique identifier inspired by Stripe IDs
Assuming you don't need to use UUIDv7 (or any UUID's) then https://github.com/segmentio/ksuid provides a much bigger keyspace. You could just append a string prefix if you wanted to namespace, but the chance of collisions of a KSUID is many times smaller than a UUID of any version.

Unexpected downsides of UUID keys in PostgreSQL
KSUID's are have temporal-lexicographical order plus 128 bits of entropy, which is more than UUIDv4.

UUIDs are so much better than autoincrementing ids and it's not even close
That's why you use ksuid (https://segment.com/blog/a-brief-history-of-the-uuid/) or, if you're willing to go with a draft spec you could go with the new UUID formats https://www.ietf.org/archive/id/draft-ietf-uuidrev-rfc4122bi...

Interesting in more history of UUIDs? Twilio Segment's blog has an amazing history lesson about how they came to be.
