Thanks for that Tom, I appreciate it.

I'm just not sure what this part means

*      7   shared memory key (not present on Windows)

This corresponds to the line  " 5432001   2195471"

======================================
[pol@localhost inst]$ more ./data/postmaster.pid
7382
/home/pol/Downloads/software/postgres/inst/./data
1430769205
5432
/tmp
localhost
  5432001   2195471
[pol@localhost inst]$
=======================================


I did Google "PostgreSQL shared key" and couldn't find
anything significant - why are there two numbers?
