Thread: Simple CustomScan example
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?

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

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 -- Michael
