While running some tests, I encountered a situation where pgbench gets stuck in an infinite loop, consuming 100% cpu. The setup was:
- Start postgres server from the master branch - Initialise pgbench - Run pgbench -c 10 -T 100 - Stop postgres with -m immediate
That is a strange test to run, but it would be better if the behavior was not that one.
Well, I think it's a very legitimate test, not for testing performance, but testing crash recovery and I use it very often. This particular test was run to catch another bug which will be reported separately.
