Hm ... it's kind of annoying that that doesn't work; it's certainly not
hard to imagine use-cases for per-user or per-database settings of
local_preload_libraries. However, I'm not sure if we apply per-user or
per-database settings early enough in backend startup that they could
affect library loading. If we do, then the ALTER code needs to be
taught to allow this.
