Remember that we already have quite a lot of extensions. And PGXN. Are we really so wedded to the idea of extensions "living" outside of the database that we need to come up with something different and incompatible? Or do you envision modules or packages to be compatible with extensions? Just putting another label on it so we can still claim extensions are strictly external to the database? Sorry, I don't get the idea, there. >From a users perspective, I want extensions, modules, or packages to be managed somehow. Including upgrades, migrations (i.e. dump & restore) and removal. The approach of letting the distributors handle that packaging clearly has its limitations. What's so terribly wrong with Postgres itself providing better tools to manage those? Inventing yet another type of extension, module or package (compatible or not) doesn't help, but increases confusion even further. Or how do you explain to an author of an existing extension, whether or not he should convert his extension to a module (if you want those to be incompatible)? If it's the same thing, just with different loading mechanisms, please keep calling it the same: an extension. (And maintain compatibility between the different ways to load it.) I fully agree with the fundamental direction of Dimitri's patch. I think Postgres needs to better manage its extensions itself. Including dump and restore cycles. However, I think the implementation isn't optimal, yet. I pointed out a few usability issues and gave reasons why "template" is a misnomer (with the proposed implementation). "Extension" is not. (I still think "template" would be a good mental model.
