The session startup/shutdown should be the same for the real SQL and the broken SQL, shouldn't it? [Artur ZajÄc] > time psql -c 'explain analyze SELECT te.idt FROM t_positions AS te > JOIN t_st AS stm ON (te.idt=stm.idt AND 4=stm.idm) WHERE te.idtr IN > (347186)' Is this weidness only observed for this query? What happens with other queries? "explain analyze select 1"? "explain analyze select * from t_positions where idtr=347816"? plain select without "explain analyze"? etc? -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
