Sorry, I do this over and over until xxx.000 rows but I do not write in the mail.What "same result"? You only ran it up to 2K rows, not 2M. In any
I do it again. initdb, create table, insert, vacuum full analyze, explain analyze at each stage.
And there was no problem.So I make a copy of the offending data directory, and try again. And I got IndexScan only.
I will get an headheak ;-) Too big to be send by mail: http://rilk.com/pg81.html Cordialement, Jean-Gérard Pailloncy
