Tom I don't understand this. Your arguments above are great but let's
be realistic. I am offering something that even *I* could do with code
that is simple and useful.
You are offering what appears to be a "solution". A perfectly valid one
in fact. Which one is going to get done first? Which one is going to
provide immediate benefit?
I can't realistically code change the code for the first problem. I
might be able to hack my way through the second, I guarantee you I
could do my solution.
So why is it such a bad thing to implement something incrementally
useful? Especially considering my incremental solution doesn't
conflict with your todo for pg_autovacuum?
Sincerely,
Joshua D. Drake
