Yes, I enter query manually while testing. Here are explain plans :

for select count(*) from poll_3 where eid = 72333

"  ->  Seq Scan on poll_3  (cost=0.00..34650.40 rows=18893 width=0)"
"        Filter: (eid = 72333)"

"        ->  Seq Scan on poll_2 poll  (cost=0.00..34993.84 rows=18527

Do you have appropriate check constraints defined on table poll? Can you include a \d poll?

Also, what version is this?
