The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/9.2/static/kernel-resources.html
Description:
Documentation says:
sysctl -w vm.overcommit_memory=2
"it will lower the chances significantly and will therefore lead to more
robust system behavior."
This statement in documentation is Wrong.
This is not recommended for production environments, because if an
out-of-memory condition does present itself, there could be unexpected
behavior.
