PostgreSQLMemory Management<br /> To: <a href="mailto:pgsql-general@postgresql.org">pgsql-general@postgresql.org</a><br
/><br/><br />Hi All,<br /><br />I have a few general question about PGSQL's internals of memory management and I think
thislist is appropriate for that. I am interested to find out:<br /><br />(1) how does PostgreSQL internally use
physicalmemory allocated to it?<br /> (2) what are different type of allocation units?<br /> (3) what is a particular
allocationunit used for e.g., to store log-tail, query plans, procedure cache etc.?<br /><br />I've already gone
throughREADME file in /backend/src/util/mmgr.<br /><br />Thanks,<br /><font color="#888888">-Umar<br /></font></div><br
