PostgreSQL Not Starting: FATAL: could not write lock file “”: No space left on device

I have a couple development servers I have been using for testing PostgreSQL configured with walmgr for log shipping. The secondary server stopped working the other day and I finally got a chance to look into it this morning and attempted to restart Postgres via a terminal but it failed. Below I describe how the error was noticed, what was done to troubleshoot PSQL not starting, and what was done to resolve the problem so PostgreSQL would start without issue.
