Possible to exclude a database from loading a shared_preload_libraries module?

Hi, I have a use case where I want a particular database to not load a few
modules in shared_preload_libraries.
I was wondering if there's any way to tweak the codebase to achieve this.

No. It's not even theoretically possible, because the whole point of
shared_preload_libraries is that the module gets loaded at postmaster
start.

Depending on what the module does, it might work to load it
per-session with session_preload_libraries, which you could attach
to the specific database(s) where you want it to be effective.

Otherwise, can I block the modules' hooks/bgw from performing actions on my
particular database?

That would be a feature for the individual module to implement.
