That's not a question, that's a well-established fact --- pl/R certainly
needs it, and any other library that has expensive setup work that can
propagate through a fork does too.

I think adding a hook to allow a postmaster-preloaded library to execute
some work immediately post-fork is a separate consideration. Feel free
to propose it if you want, but I don't see what it's got to do with the
patch on the table.
