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.? I've already gone through README file in /backend/src/util/mmgr. Thanks, -Umar
