You guys were right
:Jun 17 11:04:57 kernel: Out of Memory: Killed process 24928 (postmaster).
I did not disable memory overcommit. I guess this is something I will
have to do. I have actually never seen this before or heard of memory
overcommit. I am surprised a setting like this comes enabled by default.
I read a bit about it and it seems to make sense to disable it, but from
practical experience do you know of any negative side effects?
