Hello!
While I was using pgbench from the master branch, I discovered an error on
pgbench logs.
When I run pgbench, the log file contains a lot of redundant 0s.
I ran git bisect and found out that this error occured since the commit
547f04e7348b6ed992bd4a197d39661fe7c25097 (Mar 10, 2021).
I ran the tests below on the problematic commit and the commit before it.
(I used Debian 10.9 and Ubuntu 20.04)
=====
./pg_ctl -D /tmp/data init
./pg_ctl -D /tmp/data start
./pgbench -i -s 1 postgres
./pgbench -r -c 1 -j 1 -T 1 --aggregate-interval 1 -l --log-prefix
pgbench-log postgres
./pgbench -r -c 2 -j 4 -T 60 --aggregate-interval 1 -l --log-prefix
pgbench-log postgres
./pgbench -r -c 2 -j 4 -T 60 --aggregate-interval 10 -l --log-prefix
pgbench-log postgres
=====
The result screenshots are in the attachments.
(I didn't attach the problematic 60 second log file which was bigger than
1GB.)
Please take a look at this issue.
Thank you!
Regards,
YoungHwan
