Hello.
There is a task "Sequential disk access during VACUUM for GiST/GIN " in list GSOC14.
Nobody is working on this task?
Do I understand this task correctly?
I must recode gistbulkdelete.
GistBDItem *stack is must have items with sequential blkno as possible.
I have a question:
where are access to disk in this function? ReadBufferExtended?
Thanks
