PostgreSQL version: 8.3.4
Operating system: Linux 2.6.24
Description: autovacuum working send SIGUSR1 to the wrong pid
Details:
I was running postgres on a Linux with busybox. The autovacuum feature is
turned on. I noticed that the autovacuum worker sent SIGUSR1 to pid 1 which
is the init process and caused the system halt.
Hmm. The postgres user shouldn't have permission to halt the system,
methinks.
I did some debugging and found that the root cause is the constant
AutoVacNumSignals is not defined correctly. It should be (AutoVacRebalance +
1).
Yeah, that's clearly a bug. Fixed, thanks.
