So we should keep all the work out of the tree until every part is done?
No thanks; especially not when there is a perfectly respectable use-case
for parts X and Y alone (whether it suits *your* uses or not).

How much testing has pg_standby really gotten? Some, sure, but it's a
contrib module that wasn't even there before 8.3. Even ignoring the lag
issue, I wouldn't trust it a whole lot if I were a DBA responsible for
valuable data. As much as some folk would like to think that contrib
is mainstream, it's not really in the same league as far as testing
coverage goes.
