Subject: Getting OOM errors from PostgreSQL

In my log I have been getting errors that look like this:
LOG:  could not fork new process for connection: Cannot allocate memory

This seems to only happen during periods of high activity. Shortly after the last one occurred I checked the free mem and got this:
# free -h
              total        used        free      shared  buff/cache   available
Mem:           9.4G        737M        283M        2.1G        8.4G        6.3G
Swap:          2.0G        8.3M        2.0G
