Hi,
I've been trying to run some pg_ctl command inside a python script,
and saw that some of them where deadlocking. It seems that the
commands that start postgres handle stdout in a way that that block
the caller. Redirecting stdout to /dev/null or to a file using the -l
option allow me to workaround the problem, but fixing it upstream
would be nice.
Here's a simple python program that reproduces the problem, and should deadlock.
Customize your data path first, of course.
Regards,
