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

mod team resignation by BurntSushi · Pull Request #671 · rust-lang/team
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.
