pg_prewarm: Add automatic prewarm feature. Periodically while the server is running, and at shutdown, write out a list of blocks in shared buffers. When the server reaches consistency -- unfortunatey, we can't do it before that point without breaking things -- reload those blocks into any still-unused shared buffers. Mithun Cy and Robert Haas, reviewed and tested by Beena Emerson, Amit Kapila, Jim Nasby, and Rafia Sabih.
