Hi, yes, I'm cheating by using GUI :) (PgAdmin) Here: "Aggregate (cost=18240.50..18240.51 rows=1 width=0) (actual time=2911.117..2911.119 rows=1 loops=1)" " -> Seq Scan on min1_009 (cost=0.00..18108.60 rows=52760 width=0) (actual time=5.390..2816.274 rows=52760 loops=1)" "Total runtime: 2912.211 ms" -----Original Message----- From: Alban Hertroys [mailto:haramrae@xxxxxxxxx] Sent: 7. lokakuuta 2013 12:31 To: Toni Helenius Cc: pgsql-general@xxxxxxxxxxxxxx Subject: Re: Index only select count(*) On Oct 7, 2013, at 11:23, Toni Helenius <Toni.Helenius@xxxxxxxxxxxxxxx> wrote: > The output of analyze: > "Aggregate (cost=18240.50..18240.51 rows=1 width=0)" > " -> Seq Scan on min1_009 (cost=0.00..18108.60 rows=52760 width=0)" That's the output of Explain, not of Explain Analyze.
