I like it, but I'm not sure there's enough consensus for that. I've
suggested before including install info inside the modules themselves
but there doesn't seem to be much interest in that.

Apart from that there's issues with implementation. The Linux kernel
can do it easily because it knows it will be using ELF, thus can use
sections to store this info. Postgresql has to support many more types,
making things like this tricky (but not impossible).

Personally I'd like postgres to move to a system where external modules
can easily be installed, uninstalled and upgraded. However, I've not
seen the demand yet.

Have a nice day
