I have applied attached patch, set shared_buffers to 128kB and ran pgbench,
I am able to see below distinct IO events.
--with ./pgbench -i -s 500 postgres
application_name wait_event_type wait_event query
pgbench IO ExtendDataBlock
copy pgbench_account
pgbench IO WriteXLog
copy pgbench_account
pgbench IO WriteDataBlock
copy pgbench_account
pgbench IO ReadDataBlock
vacuum analyze pgben
pgbench IO ReadBuffile
alter table pgbench_
--with ./pgbench -T 600 postgres (readwrite)
application_name wait_event_type wait_event query
pgbench IO ReadDataBlock
UPDATE pgbench_accou
pgbench IO WriteDataBlock
UPDATE pgbench_telle
IO SyncDataBlock
pgbench IO SyncDataBlock
UPDATE pgbench_telle
IO SyncDataBlock
autovacuum: VACUUM A
pgbench IO WriteXLog
END;
pgbench IO ExtendDataBlock
copy pgbench_account
--with ./pgbench -T 600 -S postgres (select only)
application_name wait_event_type wait_event query
pgbench IO ReadDataBlock
SELECT abalance FROM
Attached excel with all IO event values.
