Immediate use cases for me would be
* ability to filter WAL records based on database or relation
* ability to recover quickly from various types of bug, for example if
new freespace code caused a corruption we would be able to sidestep it
and get the database up again quickly without doing resetxlog and losing
data.
Medium term
* bit map indexes
But this isn't just for me...
