On Windows hosts, preloading a library at server start will not reduce
the time required to start each new server process; each server process
will re-load all preload libraries. However, <varname>shared_preload_libraries
</varname> is still useful on Windows hosts because some shared libraries may
need to perform certain operations that only take place at postmaster start
(for example, a shared library may need to reserve lightweight locks
or shared memory and you can't do that after the postmaster has started).

If a specified library is not found,
the server will fail to start.
