David,
I understand that the sort_mem conf setting affects queries with order by,
etc., and the doc mentions that it is used in create index. Does sort_mem
affect the updating of indexes, i.e., can the sort_mem setting affect the
performance of inserts?
Only if the table has Foriegn Keys whose lookup might require a large sort.
Otherwise, no.
Hmmm ... what type of foreign key lookup would that be? None of the RI
generated queries has any order by clause.
