Why we need to display memory information which represents the current state of memory

[Samrat-Revagade]

1. Why we are displaying the current state of memory to user ?
2. How that is useful for our goal ?
3. Is there any value of postgresql.conf parameter that we are fixing on the basis of this ?

as per report:

Yes, Total ram, free ram and [free_ram + swap]. These parameters are used to recommend values of shared_buffer, work_mem and wal_buffers. I used them from OS. conf file. I thought they were necessary in report to show system configuration.
