creating an index. This gathers statistics which the query planner
uses to optimize index usage.
-Note that PostgreSQL may occasionally not use the GiST indexes when
-performing searches. If you find your system is not using the
-indexes automatically (use 'EXPLAIN' to see the query plan)
-you can force index use with the command:
-
- SET ENABLE_SEQSCAN = OFF
-
-Try doing an EXPLAIN on your query before and after the 'enable_seqscan'
-command to see the different query plans.
