Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

A Bit Overcomplicated
At the risk of sounding stupid, I have no idea how bit-shifting and bitwise operators work, though I've worked in the field for over a decade and am now a Staff Engineer or whatever. There, I said it.
It's just something I haven't gotten around to reading yet. I suspect some code would be made clearer by it, but even when doing something similar I wound up using the math textbook was to do it even though I suspect the bit operators would be much faster.

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...

What Happened to UUIDv2?
Interesting in more history of UUIDs? Twilio Segment's blog has an amazing history lesson about how they came to be.

Which UUID package do you use? and why?
I use the ksuid from segment. https://github.com/segmentio/ksuid
