Thread: pgsql: Use streaming read I/O in SP-GiST vacuuming
Use streaming read I/O in SP-GiST vacuuming Like 69273b818b1df did for GiST vacuuming, make SP-GiST vacuum use the read stream API for vacuuming physically contiguous index pages. Concurrent insertions may cause SP-GiST index tuples to be redirected. While vacuuming, these are added to a pending list which is later processed to ensure no dead tuples are left behind. Pages containing such tuples are still read by directly calling ReadBuffer() and do not use the read stream API. Author: Andrey M.
