I don't know why seq scan is running on the following query where the
same query is giving index scan on other servers:
explain analyze
select *
from act
where act.acttype in ( 'Meeting','Call','Task');
QUERY PLAN
----------------------------------------------------------------------------------------------------------------------------------------
Seq Scan on act (cost=0.00..13386.78 rows=259671 width=142) (actual
time=0.013..484.572 rows=263639 loops=1)
Filter: (((acttype)::text = 'Meeting'::text) OR ((acttype)::text =
'Call'::text) OR ((acttype)::text = 'Task'::text))
Total runtime: 732.956 ms
(3 rows)
Al, what percentage of the rows fits the above criteria? How big are
your histograms?
