The above wiki states that "if a query involves doing merge sorts of 8 tables, that requires 8 times work_mem." If I have a table that is partitioned does each partition count as a "table" and get its on work_mem?
For example, say I have the following table partitioned by the time column:
CREATE TABLE values (time TIMESTAMP, value INTEGER);
If I do the following query will it require 1 work_mem or N work_mem's (where N is the number of partitions)?
