Hi,

This is my first proposal of PITR performance improvement for
PostgreSQL 8.4 development.   This proposal includes readahead
mechanism of data pages which will be read by redo() routines in the
recovery.   This is especially effective in the recovery without full
page write.   Readahead is done by posix_fadvise() as proposed in
index scan improvement.

Details of the implementation will be found in README file in the material.
