Hi All,

I have a few general question about PGSQL's internals of memory management and I think this list is appropriate for that. I am interested to find out:

(1) how does PostgreSQL internally use physical memory allocated to it?
(2) what are different type of allocation units?
(3) what is a particular allocation unit used for e.g., to store log-tail, query plans, procedure cache etc.?


Thanks,
-Umar
