Hello.
Did you vacuum postgresql DB before the count(*). I ask this because
(unless table was created& loaded in same transaction) on the first
scan, postgresql has to write hint bits to the whole table. Second scan
may be way faster.
Best regards, Vitalii Tymchyshyn
Vitalli, yes I did vacuum before the count.
