I'll repeat a remark I have made exactly yesterday on a different
thread: having a test module for custom scans in src/test/modules/ to
test these APIs and have a usable template would be welcome :D

Is anyone aware of code with a simple example of a custom scan? 


You may find the one in this repo: https://github.com/bdrouvot/pg_directpaths 
simple enough.

Simple CustomScan example

[Chris Cleveland]

I'm trying to write a custom scan. It's pretty confusing. I've read the
documentation at
https://www.postgresql.org/docs/current/custom-scan.html, and I've scanned
the
code in Citus Columnar and in Timescale, both of which are quite complex.

Is anyone aware of code with a simple example of a custom scan? Or maybe a
tutorial?
