Can anybody briefly explain me how each postgres process allocate memory for it needs? I mean, what is the biggest size of malloc() it may want? How many such chunks? What is the average size of allocations?
I think that at first it allocates contiguous piece of shared memory for "shared buffers" (rather big, hundreds of megabytes usually, by one chunk). What next? temp_buffers, work_mem, maintenance_work_mem - are they allocated as contiguous too? What about other needs? By what size they are typically allocated? -- antonvm -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
