On its core, cats basically provides a bunch of typeclasses (like Functor, Monad, Monoid) organized in a hierarchy.

doobie map to PostGIS Point
So you need to use PGgeography scala type and import another set of implicits: https://github.com/tpolecat/doobie/blob/main/modules/postgres/src/main/scala/doobie/postgres/pgisgeographyinstances.scala

Developer removing a library integration due to above politics
- Remove Quill Integration

It's unsafe to depend on Typelevel Libraries
Doobie removes Quill integration in order to make some sort of political protest. The Quill developers are harassed on Twitter.
- Why is tpolecat against ZIO?
- Removes integration with Quill, which is now part of the ZIO organization, which I will not support

Zio / Zionomicon : is it worth it ?
The libraries doobie and skunk are more closely associated with cats. They both use cats-effect and fs2 for implementing database connectiona and input-output operations. The doobie library is a wrapper on JDBC, and as such is compatible with many DBMS, such as MySQL, PostgreSQL, H2, Oracle... Whereas skunk is specific to PostgreSQL, and is based on using the server protocol of that database.

Hiding Doobie's ConnectionIO implementation detail
You may find this issue helpful. tl;dr you can easily make a Transactor with the void Strategy that just ignores the null Connection. But I’m with Rob: at that point, you’re not actually testing anything.
What are some alternatives?
Slick - Slick (Scala Language Integrated Connection Kit) is a modern database query and access library for Scala
Quill - Compile-time Language Integrated Queries for Scala
skunk - A data access library for Scala + Postgres.
ScalikeJDBC - A tidy SQL-based DB access library for Scala developers. This library naturally wraps JDBC APIs and provides you easy-to-use APIs.
Anorm - The Anorm database library
Clickhouse-scala-client - Clickhouse Scala Client with Reactive Streams support
PostgreSQL and MySQL async
mongo-scala-driver
scala-redis - A scala library for connecting to a redis server, or a cluster of redis nodes using consistent hashing on the client side.
scala-migrations - Database migrations written in Scala
Squeryl - A Scala DSL for talking with databases with minimum verbosity and maximum type safety
ReactiveMongo - :leaves: Non-blocking, Reactive MongoDB Driver for Scala
