I certainly have no concerns.

I think eventually we should put pglesslog into /contrib, and if we ever
do that, we would update your web page. I have not heard any mention of
it being moved into /contrib for 8.4 though.

If you would like me to point to another URL, please let me know.

I think there is definately demand for pglesslog because not only does
it truncate dead space from the WAL file, it also removes full page
write images, and is best done in archive_command, and hence externally
like your tool does.

Sorry, I don't know enough about pg_readahead.
