Thank you. I played a bit with this patch, and can confirm visible WAL size reduction (it's rather obvious, but still). Although, probably due to lack of my knowledge here, I wonder how does it work when an index is build concurrently? > Benchmarks: > ----------- > > Test: pgbench -f gin-WAL-test.sql -t 5: > --------------------------------------- > master: > Latency average: 27696.299 ms > WAL size: 2.66 GB Does it makes sense to measure latency of the entire script, since it contains also some preparation work? Of course it still shows the difference between patched version and master, but probably in a more noisy way. I'm moving this patch to the next CF.
