I built a cookiecutter template for Postgres extensions.
This cookiecutter prompts for some basic extension metadata (e.g., name, Postgres version) and then automatically generates the necessary boilerplate files.
These include:
* Standard extension files (Makefile, .control, c, .h, .sql) pre-populated with stubs. * Regression Tests * GitHub Actions for building and testing on multiple Postgres versions * Docker support * pgxn integration
