Hi,
Make
multi-column indexes, using the columns from your most typical queries, putting
the most selective columns first (ie; you don't need to make indexes with
columns in the same order as they are used in the query).
For
instance, an index on cp, effectif could likely benefit both
An index
on cp and effectif would help your first query. An index on naf, cp and effectif would help your second
query.
Something
like this:
CREATE INDEX base_aveugle_cp_key2 ON
base_aveugle USING btree (cp, effectif);
CREATE INDEX base_aveugle_naf_key2 ON base_aveugle USING btree
