Commits 9ff60273e35cad6e and dbe2328959e12701 adjusted the declarations of some core functions referenced by contrib/tsearch2's install script, forgetting that in a pg_upgrade situation, we'll be trying to restore operator class definitions that reference the old signatures. We've hit this problem before; solve it in the same way as before, namely by installing stub functions that have the expected signature and just invoke the correct function. Per report from Jeff Janes. (Someday we ought to stop supporting contrib/tsearch2, but I'm not sure today is that day.)
